• Simple tin derivatives, Cp* 2 SnCl 2 ( 1 ) and Ph 2 SnCl 2 ( 2 ), catalyze the hydrophosphination of alkene substrates with diphenylphosphine. Competitive dehydrocoupling to give Ph 4 P 2 was observed, but this side reaction can be mitigated when the catalysis is conducted under an H 2 atmosphere. Efforts to prepare stable tin bis(phosphido) compounds commonly resulted in decomposition to Ph 4 P 2 . Lewis acidic inorganic tin compounds do not show dehydrocoupling reactivity. It was found that the Lewis acid, B(C 6 F 5 ) 3 , is able to engage in the hydrophosphination of alkenes, but it is poorly effective under the conditions tested. Simple tin derivatives, Cp* 2 SnCl 2 ( 1 ) and Ph 2 SnCl 2 ( 2 ), catalyze the hydrophosphination of alkene substrates with diphenylphosphine.
