摘要
研究了二羰基乙酰丙酮铑Ｒｈ（ａｃａｃ）（ＣＯ）２对苯乙烯，Ｐ－甲基苯乙烯氢甲酰化反应的催化性能．在常压下，Ｒｈ（ａｃａｃ）（ＣＯ）２和Ｐ（ＯＰｈ）３、ＰＰｈ３、Ｐｈ２Ｐ（ＣＨ２）ｎＰＰｈ２（（ｎ＝２，３）组成的体系具有较好活性．在双齿配体存在下，２－芳基丙醛的选择性可达９５％以上．
Hydroformylation of styrene and p-methylstyrene catalyzed byRh(acac) (CO)2(acac=acetylacetonate)has been studied under atmospheric pressure.The complex combined with P (OPh)3,PPh3 and Ph,P (CH2)nPPh2 (n=2, 3 )shows highercatalytic activity. UP to 95% of 2-arylpropanal can be obtained in the presence ofdiphosphine ligands.
