title: Rhodium-catalyzed regioselective olefin hydrophosphorylation.
abstract: 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]
