  Palladium(II)-Catalyzed Conjugate Phosphination of Electron-Deficient Acceptors

  摘要：

  A general protocol for the conjugate transfer of diphenyl-, dicyclohexyl-, and di-tert-butylphosphinyl groups from silylphosphlnes to cyclic and acyclic electron-deficient acceptors employing a bench-stable palladium(II) catalyst Is reported. Several E and Z configured alpha,beta-unsaturated carbonyl and carboxyl acceptors (including imides) as well as nitroalkenes participate in this palladium(II)-catalyzed process in high chemical yields.

  rhodium(I) by means of an RhI–OH complex, enables the conjugate transfer of nucleophilic silicon onto α,β-unsaturated acceptors. Pre- or in situ formed cationic rhodium(I)–binap complexes catalyze this novel carbon–silicon bond formation with exceptional enantiocontrol, 92 to >99% ee for cyclic carbonyl and carboxyl compounds as well as >99% ee for acyclic carboxyl compounds.

  铑（I）催化的硅-硼键活化，即通过Rh I -OH络合物将硅从硼转变为铑（I），可以将亲核硅共轭转移到α，β上-不饱和受体。预制的或原位形成的阳离子铑（I）-联萘酚配合物可催化这种新型的碳-硅键形成，具有出色的对映体控制能力，环状羰基和羧基化合物的ee为92％至> 99％ee，无环羧基化合物的ee> 99％。

  The Rh(I)-catalyzed conjugate phosphinyl transfer from an Si–P reagent to an electron-deficient acceptor requires individual protocols for cyclic and acyclic α,β-unsaturated carbonyls and carboxyls. While 1,4-addition to cyclic acceptors is catalyzed by a Rh(I)–phosphine complex, a Rh(I)–carbene complex is needed to promote conjugate phosphination of acyclic acceptors. General procedures for both systems

  从Si-P试剂到缺电子受体的Rh（I）催化的共轭亚膦酰基转移需要针对环状和非环状α，β-不饱和羰基和羧基的单独方案。尽管Rh（I）-膦配合物可催化向环受体加成1,4-，但需要Rh（I）-卡宾配合物来促进非环受体的共轭磷酸化。报告了这两个系统的一般步骤。除了单膦源化的Si-P试剂作为次膦化物来源外，具有两个Si-P单元的dppe-以及dppp衍生的试剂也参与了该反应。这种Rh（I）催化Si-P试剂活化的机制仍在争论中。使用对映纯硅立体异构和外消旋磷立体异构Si-P试剂进行的对照实验支持催化从重金属化而不是氧化加成开始。包括本研究中使用的Si-P化合物的制备和全部表征数据。
