Triazidochlorosilane (SiCl4-NaN3 in situ) is a new and efficient reagent for the direct conversion of ketones or α,β-unsaturated ketones to the corresponding tetrazole derivatives in nearly quantitative yield.

TETRAZOLES. XXVIII PREPARATION AND PROPERTIES OF 2,3-DIPHENYL-5-ALKYLTETRAZOLIUM SALTS

The oxidation of 1,5-diphenyl-3-alkylformazanes by potassium permanganate in methylene chloride (chloroform)-water two-phase systems is a convenient method for the preparation of 2,3-diphenyl-5-alkyltetrazolium salts.The 2,3-diphenyl-5-alkyltetrazolium salts can be used as catalysts for interphase transfer in reactions proceeding in organic solvent-water two-phase systems, with a neutral or acid aqueous phase.The catalytic activity of 2,3-diphenyl-5-alkyltetrazolium salts increases with increase in the length of the alkyl substituent in the 5-position of the tetrazole ring.
