Abstract
A new oxapalladacycle 3 can be conveniently prepared via direct ortho palladation of diphenylphosphinic acid with palladium acetate. Catalysts derived from 3 can efficiently catalyze Markovnikov-type additions of E-H bonds (P(O)-H, S-H and spC-H) to alkynes via a unique catalytic cycle.
摘要
一种新的邻位钯化膦酸二苯酯 3 可以通过醋酸钯直接邻位钯化膦酸二苯酯方便地制备。由 3 衍生的催化剂可以通过独特的催化循环有效地催化 E-H 键（P(O)-H、S-H 和 spC-H）与炔烃的马氏加成反应。
