摘    要:本文研究了由Rh2(CO)4CI2分别与两种膦配体4-下丁苯基二苯基膦(1)和4-正辛苯基二苯基磷(2)形成的原位催化剂体系对烯烃氢甲酰化反应的催化性能。对影响反应的各种因素,如P/Rh物质的量比、反应温度、反应压力,不同烯烃等的影响作了探讨。结果表明,配体1、2与Rh2(CO4)CI2形成的原位催化剂体系的催化活性与选择性均高于结构相似的PPh3,在相同的条件下,不同烯烃的氢甲酰化反应活性依直链烯烃>苯乙烯>直链内烯>环己烯的顺序递增。

关 键 词:烯烃  氢甲酰化反应  铑-膦配位催化剂  催化活性

Abstract:This paper studied the catalytic propesties of the catalysts in situformed by Rh 2(CO) 4Cl 2 and 4 butylphenyl diphenylphosphine (1) and/or 4 octyl phenyl diphenylphosphine (2) for the hydroformylation of 1 hexene.The influence of various parameters,such as the molar ratio of rhodium to phosphine,the reaction temperature and pressure on the hydroformylation were investigated.As ligand,phosphine 1 and 2 exhibited higher activity and selectivity than triphenylphosphine.This may be attributed to the electronic and steric effects of alkyl group on the aromatic ring.When using Rh 2(CO) 4Cl 2 as catalytic precursor and 1 as ligand,the rate of hydroformylation of various olefins decreased in following order:terminal olefin>styrene>internal olefin>Cyclohexene.
Keywords:Rh  2(CO)  4Cl  2  phosphine  olefin and hydroformylation
