• Potassium-Catalyzed Hydrosilylation of Activated Olefins: Evidence for a Silyl Migration Mechanism

  The alkali-metal silyl [K(L)SiPh3] (1; L = 18-crown-6 ether) catalyzed the hydrosilylation of activated C=C double bonds. Isolation and characterization of an addition product is in agreement with the anti-Markovnikov selectivity. Second-order kinetics for the hydrosilylation of 1,1'-diphenylethylene and the kinetic isotope effect of k(H)/k(D) = 3.1 indicate that a silyl migration mechanism is operative.
