Selective 1,2-hydrosilylation of 1,3-dienes is a challenging problem in transition metal catalysis. Butadiene, specifically, would be a useful substrate because 3-butenylsilane products have promise as superior coupling reagents for hybrid organic/inorganic materials synthesis. We report the first selective 1,2-hydrosilylation of conjugated dienes including butadiene. Hydrosilylation proceeds through a Pt(II/IV) cycle, and selectivity is generated at a hexacoordinate Pt(IV) complex that favors 2-diene coordination and prevents π-allyl complex formation.

The THF solutions of (triethoxysilyl)methyl magnesium chloride are stable at low temperatures. At 20°C, the Grignard reagent underwent intermolecular condensation, providing a simple synthesis of cyclic carbosilanes derivatives. The cross-coupling reaction with organic halides also afforded a facile route to a variety of trifunctional organosilicon compounds.
