摘 要: | As a versatile one-electron transfer reducing and coupling agent, samarium diiodide has been extensively used in organic synthesis in last decade. It has been reported that electrophilic p-allyl palladium complexes could undergo polarity inversion to nucleophilic species with the aid of SmI2, and could trap some electrophiles1. It is well known that allylic selenides are rather important intermediates in organic synthesis. They have been recognized as useful synthons of allylic anion stabi…
