Multifunctional transformation of amide C–N bond cleavage is reported. The protocol applies to benzamide, thioamide, alcohols, and mercaptan under similar reaction conditions catalyzed by NaOTs. It is noteworthy that NaOTs can not only be recycled and reused for up to three cycles without significant loss in catalytic activity, but also catalyze gram-grade reactions. This study provides a novel solution
Europhtal: An industrial cobalt phthalocyanine complex as the efficient catalyst for synthesis of thioamides by one‐pot reaction of mercaptans and amines
The potential of industrial cobaltphthalocyanines in the synthesis of thioamides is reported. A mixture of an industrial sulfonated cobaltphthalocyanines known as Co[(SO3Na)2,3Pc] (Europhtal catalyst additive 8020) is introduced as an efficient catalyst capable of converting benzyl thiols to synthetically valuable thioamides by reaction with amines and DMSO. In this procedure, different primary and

modifies the properties of valuable thioamide isosteres for the development of newmethods in organic synthesis. We fully expect that in analogy to the burgeoning field of destabilized amides introduced by our group in 2015, the thioamide bond ground-state-destabilization activation concept will find broad applications in various facets of chemical science, including metal-free, metal-catalyzed and metal-promoted
