[摘要]A review. The development of Pd-catalyzed carboetherification and carboamination reactions between aryl or alkenyl halides and alkenes bearing pendant heteroatoms is described. These transformations effect the stereoselective construction of useful heterocycles, such as tetrahydrofurans, pyrrolidines, imidazolidin-2-ones, isoxazolidines, and piperazines. The scope, limitations, and applications of these reactions are presented, and current stereochem. models are described. The mechanism of the product formation, which involves an unusual intramol. syn-insertion of an alkene into a palladium-heteroatom bond, is also discussed in detail.
