Thiocarbonyl Transfer Reagent Chemistry. 3. Selective Displacements with Formaldehyde Hydrazones and Other Nucleophiles

Article abstract of DOI:10.1021/jo00325a007

Formaldehyde hydrazones react with 1,1'-thiocarbonylbis(1,2,4-triazole) to effect C-thioacylation.The 1,2,4-triazole leaving group on these stable thioglyoxylic acid derivatives could in turn be displaced by hydrazones, sulfonohydrazides, thiosemicarbazid
