摘要:
This review covers those domino reactions that involve, at least, both palladium-catalyzed dehydrogenation of carbonyl compounds and Heck-type reactions. While the former occurs under Pd(II) catalysis, a Pd(0) or Pd(II) catalyst is required for the latter, depending on the nature of the (hetero)arylating agent, ArX or ArH, respectively. Regeneration of the Pd(II) species is assumed to proceed by either an oxidant or the aryl halide. Proposed mechanisms are described with, in some cases, personal comments.
