METHOD OF PRODUCING N',N'-BIS{[ALKYL(PHENYL)SULPHANYL]METHYL}ARYLHYDRAZIDES Russian patent published in 2014 - IPC C07C241/04 C07C319/14

Abstract RU 2504537 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing N',N'-bis{[alkyl(phenyl)sulphanyl methyl]}arylhydrazides. The method involves reacting alkyl(phenyl)thiol RSH with aqueous formaldehyde and hydrazide ArC(O)NHNH₂ in the presence of a samarium chloride crystalline hydrate catalyst SmCl₃-6H₂O at temperature of 75-85°C for 22-26 hours. Output of N',N'-bis{[alkyl(phenyl)sulphanyl methyl]} arylhydrazides is 80-97%.

EFFECT: described is a novel method of producing arylhydrazines, which have potential as novel modified pharmacologically active agents.
