A palladium complex generated in situ from [Pd(eta3-C3H5)(cod)]BF4 and DPPF is a good catalyst for benzylic alkylation of benzyl methyl carbonate with the carbanion of dimethyl malonates. The catalytic reaction is applicable to a wide range of the benzylations of benzylic esters with malonates. The catalytic activity was heavily affected by the bite angle of the bidentate phosphine ligand on palladium
由 [Pd(eta3-C3H5)(cod)]BF4 和 DPPF 原位生成的钯配合物是用于苄基甲基碳酸酯与丙二酸二甲酯的碳负离子的苄基烷基化的良好催化剂。该催化反应适用于广泛的苄酯与丙二酸酯的苄基化反应。催化活性受到钯上双齿膦配体的咬合角的严重影响。在钯催化的苄酯的苄胺化的情况下,DPEphos 配体优于 DPPF。
