摘要 文章研究了用把单膦配体络合物催化氯苄双羰基化反应生成苯基丙酮酸甲酯的催化反应。考察了反应温度、反应压力及催化剂用量对反应产率和选择性的影响。结果表明反应压力达6.0 MPa后产率无明显变化;反应温度在373 K时,产率和选择性都达到最大值;催化剂用量有一最适宜值,配体不同此值也不同。并探讨了体系的双羰基化反应机理。 Double carbonylation reaction of C_6H_5CH_2Cl has been studied using Pd complexes with phosphorous ligands as catalyst. The effect of reaction temperature, pressure and the quality of catalyst used are also discussed in the paper.
