NEW METHODS AND REAGENTS IN ORGANIC SYNTHESIS. 59. LITHIUM TRIMETHYLSILYLDIAZOMETHANE: A NEW SYNTHON FOR THE PREPARATION OF 5-SUBSTITUTED 1,2,3-THIADIAZOLES

Lithium trimethylsilyldiazomethane smoothly reacts with thionoesters, dithioesters, and carbon disulfide to give 5-substituted 1,2,3-thiadiazoles.

Reactions of α-Polyhalo Ketone Tosylhydrazones with Sulfide Ion and Primary Amines. Cyclization to 1,2,3-Thiadiazoles and 1,2,3-Triazoles

Trichloroacetaldehyde tosylhydrazone acts as an excellent precursor of diazodithioacetate which is generated by treatment of the hydrazone with sulfide ion.This spontaneously cyclizes it to 5-mercapto-1,2,3-thiadiazole.The precursor also gives a 5-amino-1

Method for preparing 5-mercapto-1,2,3-thiadiazole salts

A method for preparing a 5-mercapto-1,2,3-thiadiazole salt represented by the general formula (I) is disclosed: STR1 the method comprises the steps of: providing a sulfonylhydrazone derivative represented by the general formula (II): STR2 providing a sulfide represented by the general formula (III): (wherein R is an aryl group, X is a chlorine or bromine atom, M is an alkali metal atom and M' is a hydrogen atom or an alkali metal atom); combining the sulfonylhydrazone derivative represented by the general formula (II) and the sulfide represented by the general formula (III) and allowing a reaction to occur; and obtaining the 5-mercapto-1,2,3-thiadiazole salt represented by the general formula (I).
