Authorship：Last author Language：English Publishing type：Research paper (scientific journal) Publisher：Georg Thieme Verlag KG
A simple, economical, and safe method for the synthesis of mesoionic 1,3-diaryltetrazolium derivatives bearing a para-substituted phenyl group at the 1- or 3-position via thiosemicarbazides was established. Such compounds were directly obtained from the corresponding para-substituted anilines instead of aryl isothiocyanates and arylhydrazines. The newly synthesized mesoionic compounds were successfully converted into the corresponding nitrosotetrazolium salts, which were utilized as catalysts for oxidation of an aliphatic alcohol and analyzed by cyclic voltammetry to determine the correlation between the catalytic efficiencies and redox potentials. The proposed method can be widely applied and is valuable for investigating the substituent effects in mesoionic and related compounds.

Pd-catalyzed bromination of mesoionic 1,3-diphenyltetrazolium-5-olate (1) was developed. In the presence of palladium acetate (5 mol%), N-bromosuccinimide (110 mol%), and p-toluenesulfonic acid (50 mol%) in 1,2-dichloroethane under reflux, olate 1 underwent bromination to give 1-(2-bromophenyl)-3-phenyltetrazolium-5-olate in a moderate yield as the major product, indicating that the 4-nitrogen atom acts as a directing group rather than the negatively charged oxygen atom. The X-ray-suitable crystals of the corresponding palladacycle were isolated from 1-mesityl-3-phentytetrazolium-5-olate and fully characterized. When both the o-positions of the 3-phenyl group were occupied by bromine atoms, o-bromination then occurred at the 1-phenyl group with the aid of the olate oxygen.

Preparative Synthesis of 1,3-Dialkyltetrazolium-5-thiolates from 1-Alkyltetrazole-5-thiols Reviewed International journal
Hirashita, Tsunehisa; Murakami, Suguru ; Shoji, Takuo; Kurabayashi, Hideaki ; Araki, Shuki
Bulletin of the Chemical Society of Japan 2021.11
Language：English Publishing type：Research paper (scientific journal)
Mesoionic 1,3-dialkyltetrazolium-5-thiolates can be prepared in good yields by alkylation of 1-alkyltetrazole-5-thiols with secondary alcohols in concentrated sulfuric acid. The thiolates are transformed into the corresponding olates through S-alkylation followed by hydrolysis. The olates were found to be liquid at room temperature and to work effectively as polar solvents. The use of a smaller amount of sulfuric acid led to drastically different products; S-bridged dimers linked by 1,2-dimethylethylene were formed as the major products.

The Mizoroki-Heck Reaction in Mesoionic 1-Butyl-3-methyltetrazolium-5-olate Reviewed International journal

Tetrahedron 99 132450 2021.10
Language：English Publishing type：Research paper (scientific journal)
1-Butyl-3-methyltetrazolium-5-olate (1), a mesoionic compound, exists as a liquid at room temperature and can be used as a polar solvent for the Mizoroki-Heck reaction, wherein it has been proven to be a superior solvent to other solvents. The reaction of iodobenzene with ethyl acrylate in the presence of palladium acetate in mesoionic liquid 1 at 40 C for 24 h gave ethyl cinnamate in 78% yield in the absence of ligands, while the use of other solvents, such as [bmim][BF4], [bmim][PF6], and DMF gave lower yields (43%, 37%, and 17%, respectively) under the same conditions. Heck-type coupling reactions of electron-deficient or electron-rich aryl iodides and bromobenzenes with olefins (15 examples, 7%–97%) were performed in 1. When a phosphine ligand was added to the reaction mixture, aryl bromides could be used, and the mesoionic liquid containing the catalysts could be reused at least five times.

Reactions between 5-Nitroso-1,3-diphenyltetrazolium Salts and Electron-rich Arenes, Reviewed International journal
Matsukawa, Yuta; Hirashita, Tsunehisa; Araki, Shuki
Bulletin of the Chemical Society of Japan 92 540 - 544 2019.01
Language：English Publishing type：Research paper (scientific journal)
A series of reactions between 5-nitroso-1,3-diphenyltetrazolium tetrafluoroborate and methoxybenzenes, amines, thiols, sulfoxides, and sulfides, most of which are generally accepted asbeing inert to nitroso groups, is reported here. The tetrazoliumactivated nitroso functionality is capable of oxidizing the aforementioned substrates to give the corresponding oxidized products, and the nitroso tetrazolium itself is transformed into the corresponding amide or hydroxyamide, depending on the nature of the reaction partners. In the case of thioanisole, an addition product was obtained.

Indium-Mediated Allylation of Carbonyl Compounds in Ionic Liquids: Effect of Salts in Ionic Liquids Invited Reviewed International journal

Molecules 2018.07
Authorship：Lead author Language：English Publishing type：Research paper (scientific journal)
The In-mediated allylation of carbonyl compounds can be performed in various types of solvents including ionic liquids. However, we have found that in [bmim][BF4] (where bmim = 1-butyl-3-methylimidazolium), the In-mediated coupling of crotyl bromide with benzaldehyde gives a complex mixture, and some additives, such as halides and amines, are crucial for the successful conversion to the corresponding γ-adduct. Instead, the addition of alcohols or water promotes the formation of the α-adduct. An asymmetric induction with up to 62% enantiomeric excess (ee) was observed employing cinchonidine as an additive in a binary solvent consisting of an ionic liquid and dichloromethane.

Nitrosotetrazolium-Catalyzed Aerobic Oxidation of Alcohols to the Corresponding Carbonyl Compounds Reviewed International journal
Yuta Matsukawa, Tsunehisa Hirashita, Shuki Araki
European Journal of Organic Chemistry 1359 - 1363 2018.02
Language：English Publishing type：Research paper (scientific journal)
A mesoionic‐nitrosotetrazolium‐catalyzed aerobic oxidation of alcohols is reported. In the presence of catalytic amounts of 5‐nitroso‐1,3‐diphenyltetrazolium tetrafluoroborate (5 mol‐%) and nitric acid (20 mol‐%), a wide range of alcohols are oxidized to the corresponding aldehydes and ketones in yields of 53–100 % at room temperature under ambient air or oxygen conditions. This oxidation shows a strong preference for secondary alcohols over primary alcohols; sterically hindered alcohols are also smoothly oxidized. A mechanism involving a nitroso/NOx catalytic cycle is proposed. -

We describe the synthesis of a mesoion-derived nitroso compound, 5-nitroso-1,3-diphenyltetrazolium tetrafluoroborate (1), and its application in the oxidation of alcohols. The structure of 1 was fully characterized by X-ray analysis, showing that it exists as a monomer in the solid state. In the cyclic voltammetric analysis of 1, a reversible redox peak was observed at 0.43 V (vs. Ag/Ag+ in MeCN) under acidic conditions. It was subsequently shown that the nitrosotetrazolium salt 1 is capable of stoichiometrically oxidizing alcohols to the corresponding carbonyl compounds effectively. This nitroso heterocycle and its reduced form, i.e., the corresponding mesoionic hydroxyamide, participate in a redox cycle involving the catalytic oxidation of alcohols by the aid of HNO3 under mild condition

Ionic TEMPO in Ionic Liquids: Specific Promotion of the Aerobic Oxidation of Alcohols Reviewed

ChemCatChem 8 2704 - 2709 2016.08
Authorship：Lead author Language：English Publishing type：Research paper (scientific journal)
The main objective of this study was to design a recyclable
TEMPO (2,2,6,6-tetramethylpiperidinyl-N-oxyl) derivative that
could be used as a catalyst in an ionic liquid solvent for the
aerobic oxidation of alcohols by using NaNO2 and HCl as cocatalysts.
To this end, a TEMPO derivative bearing a quaternary
ammonium group, [4-Bu2MeN-TEMPO][PF6] (1), was prepared.
It was subsequently shown that this ionic TEMPO derivative is
an efficient catalyst for the aerobic oxidation of a variety of primary
and secondary alcohols. It exhibits a synergistic effect
with ionic liquid solvents and readily outperforms analogous
oxidations in methylene chloride. Moreover, the ionic TEMPO
could be recycled five times with no loss of activity. -
