An unusualtrans-hydrosilylation of prochiral 1,1-disubstituted cyclopropenes revealing the different nature of asymmetric palladium and rhodium catalysis

A highly enantioselective palladium-catalyzed hydrosilylation reaction of prochiral 1,1-disubstituted cyclopropenes to access a wide variety of silylcyclopropanes bearing a quaternary carbon-stereocenter with good diastereo- and enantioselectivities.
