| 摘 要： | 考察了一系列含不同取代基团的三芳基膦配体对RhCl3催化硅氢加成的影响,结果表明：当三（2-甲氧基苯基）膦作为配体时,RhCl3能有效地催化硅氢加成,催化剂的催化活性最好;当温度达到100℃、反应5h、三（2-甲氧基苯基）膦与RhCl3催化剂的比例为5∶1时,转化率最高,催化效果最佳.

| Abstract: | The effects of a series of triarylphosphine with different substituents on RhCl3 in catalyzing hydrosilylation reaction were investigated.The results indicated that the tris（2-methoxyphenyl）phosphine ligand promotes both the hydrosilylation reaction and the catalytic activity of RhCl3.When the ratio of tris（2-methoxyphenyl）phosphine ligand and RhCl3 catalyst was 5∶1in 100 ℃,the conversion rate was the highest,and the catalytic effect was the best. |
