In recent years, the chemistry of tosylhydrazones has gained increasing attention as a result of the development of new metal-catalyzed and metal-free cross-coupling reactions.[1] In particular, the Pd-catalyzed cross-coupling of tosylhydrazones and organic halides represents a very efficient method to transform a carbonyl compound into the nucleophilic component of a CÀC bond forming cross-coupling reaction.[2] Currently, this ...
