摘要：In order to improve the selectivity of 2-methybutanal in the 1-butelene hydroformylation reaction, triarylphosphine ligands [(CnH2n+1-C6H4)(3)P (n = 4, L3; n = 6, L4; n = 8, L5; n = 10, L6)] are prepared by Friedel-Crafts alkylation reactions and characterized by H-1 NMR, C-13 NMR, P-31 NMR and HRMS. When combined with Rh(acac)(CO)(2), the L/[Rh] systems show high catalytic activity for the hydroformylation of 1-butelene. The influences of different substituents on the catalytic behavior are studied, and the effects of the molar ratio of [P]/[Rh], reaction temperature, reaction time and pressure of CO/H-2 on the yield of 2-methylbutanal are also investigated. When the ratio of [P]/[Rh] = 3, the content of 2-methylbutanal in carbonyl products reaches 48.1%. It is surprising to find the intermediate conversion in 1-butelene hydroformylation reaction and the mechanism is proposed and discussed.
