摘要
三(三苯基膦)羰基氢化铑(Ⅰ)、反式-双(三苯基膦)羰基氯化铑(Ⅰ)两种铑-膦络合物被广泛用作烯烃氢甲酰化反应的催化剂。通过改进的合成工艺合成了这两种络合物,产率高于文献报道值。通过元素分析、质谱、红外光谱和核磁共振氢谱对两种络合物进行化学结构分析,以及热重-差热分析对这两种络合物进行了热化学性质测定。
Carbonylhydridotris(triphenylphosphine)rhodium(Ⅰ)[HRh(CO)(PPh3)3],trans chlorocarbonylbis(triphenylphosphine)rhodium(Ⅰ) [trans-RhCl(CO)(PPh3)2] are widely used as the catalysts for hydroformylation of alkenes.In this paper,these two compounds were synthesized by improved methods and their yields were higher than that reported in the literatures.The chemical structures of these complexes were determined by elemental analysis,MS,IR and 1H-NMR.The thermal chemical properties were studied via TG-DTA.
