Recent Advances in Transition‐Metal‐Catalyzed Reactions of N‐Tosylhydrazones

Abstract Transition‐metal‐catalyzed reactions of N ‐tosylhydrazones provide a convenient access to various molecules by novel carbon‐carbon or carbon‐heteroatom bond formations via carbene‐type intermediates. The present review highlights recent developments in the field emphasize of the employment of different transition metals as catalysts, synthetic applications, mechanistic studies and use in domino and multicomponent reactions.
