  A Highly Selective and General Palladium Catalyst for the Oxidative Heck Reaction of Electronically Nonbiased Olefins

  摘要：

  A general, highly selective oxidative Heck reaction is reported. The reaction is high-yielding under mild conditions without the need for base or high temperatures, and the selectivity is excellent, without the requirement for electronically biased olefins or other specific directing groups. A preliminary mechanistic investigation suggests that the unusually high selectivity may be due to the catalyst's sensitivity to C-H bond strength in the selectivity-determining beta-hydride elimination step.

  Evaluation of the scope of a Pd-II-catalyzed oxidative 1,1-diarylation reaction of terminal olefins using aryl stannanes is reported. The reaction is shown to be tolerant of functionality commonly encountered in organic synthesis; however, the reaction outcome was found to be dependent on the nature of the aryl stannane used. A mechanistic rationale for the observation of this influence is provided.
