Parameters influencing the selectivity of the (PPh(3))(3)RhCl-catalyzed hydrophosphorylation of olefins and enynes are described. The reaction between differentiated dienes was shown to be highly responsive to olefin substitution. The trimethylsilyl group effectively reversed the normal preference for hydrophosphorylation of an alkyne over an alkene. [reaction: see text]
描述了影响（三苯基膦）₃氯化铑催化烯烃和烯炔的氢膦酰化反应选择性的参数。结果表明，不同二烯之间的反应对烯烃取代高度敏感。三甲基硅基有效地逆转了炔烃相对于烯烃在氢膦酰化反应中通常的优先性。[反应：见正文]
