| 摘 要： | 研究了双膦配体对铑催化的乙酸乙烯酯氢甲酰化反应的促进作用,结果表明,在优化反应条件下,以双膦化合物2,2’-二(二苯膦甲基)-1,1’-联苯(BISBI)为配体时,铑催化乙酸乙烯酯氢甲酰化反应的TOF(转化频率)值达到4000h1,生成2-乙酰氧基丙醛的选择性99%.当在较温和的条件下Rh/BISBI催化乙酸乙烯酯氢甲酰化反应较长时间时TON(转化数)值达到9200,成醛率超过90%,2-乙酰氧基丙醛选择性仍保持99%.

| Abstract: | Rhodium-catalyzed hydroformylation of vinyl acetate with the use of diphosphine ligands was studied.A high regioselectivity(branched:linear of 99:1) and activity(TOF:4000 h-1) under optimum conditions were achieved by using a 2,2’-bis(diphenylphosphino methyl)-1,1’-biphenyl ligand.The high turnover number(9200) obtained under mild conditions and stability of the catalyst indicates that it would be useful for industrial vinyl acetate hydroformylation. |
