The hydroformylation of 1-alkenes was efficiently catalyzed by PtCl2-diphosphine-SnX2 systems whose diphosphines were 1,4-bis(diphenylphosphino)butane derivatives with rigid ring skeletons.The effects of the structure of diphosphines, the P/Pt atomic ratio, the sort of tin(II) halide or solvent, the reaction variables, and the structure of olefins on the relative rate and the product distribution were investigated.A higher reaction rate than when using HRh(CO)(PPh3)3, and a linearity of aldehydes up to 99percent, were attained.The coordination structure of the effective diphosphines as well as the reasons for the rate enhancement and for the excellent selectivity were discussed.
