- A straightforward synthesis of alkyl 1H-tetrazol-5-yl thioethers via a one-pot reaction of aldehydes and 1H-tetrazole-5-thiols mediated by N-tosylhydrazones
-
A straightforward approach for the synthesis of alkyl 1H-tetrazol-5-yl thioethers from aldehydes and 1H-tetrazole-5-thiol through a one-pot procedure is presented. The aldehydes were first condensed with N-tosylhydrazine to generate the N-tosylhydrazones,

- I2-catalyzed oxidative C(sp3)-H/S-H coupling: Utilizing alkanes and mercaptans as the nucleophiles
-
By using alkanes and mercaptans as the nucleophiles with di-tert-butyl peroxide (DTBP) as the oxidant, I2-catalyzed oxidative C(sp3)-H/S-H coupling was achieved. This protocol provides a novel process to construct C(sp3)-S bonds from commercially available hydrocarbons and mercaptans.

- Tetrazoles. XXXI. Phase-Transfer Reactions of 1-Substituted Tetrazole-5-thiones and Their Derivatives
-
Alkylation of 1-substituted tetrazole-5-thiones under conditions of phase-transfer catalysis in the two-phase system liquid-liquid proceeds regioselectively at the sulfur atom, regardless of the alkylating agent and phase-transfer catalyst. Phase-transfer oxidation of the 5-alkylthiotetrazoles thus obtained by potassium permanganate is a convenient method for preparation of 5-alkylsulfonyltetrazoles which can be used to synthesize functionally substituted tetrazoles.

- Product and preparation of 1H-tetrazole-5-thiol derivatives
-
The process for preparation of and the intermediate compounds such as 1H-tetrazole-5-thiol having the formula STR1 wherein R1 is alkyl, aminoalkyl, acylaminoalkyl, aryl, alkoxycarbonylaminoalkyl, halogen-substituted aryl or alkylamino-substituted aryl and R2 is hydrogen or arakyl, preferably benzyl. The compound is produced by reacting a substituted thiosemicarbazide with an aralkyl chloride, subjecting the resultant compound to diazotization, and reacting the resultant compound with a Friedel Crafts catalyst. Optionally, this may be further hydrolyzed when R1 is aminoalkyl and/or converted to conventional salts.
