Bis(dialkylamino)carbenium salts [(Me2N)2CCl]+}2MCl42− (M=Ni, Pd) and [Me2NC(X)NR2]+}2PtCl62− (R=Me, All; X=H, Cl, Me) are efficient catalysts for hydrosilylation of allyl phenyl ether, triallylamine, allyl chloride, allylamine, and 1-octene with various hydrosilanes. The catalytic activity is dependent on the salt composition and the nature of the metal M, the saturated compound, and the hydrosilane
development of aryl alkyl sulfides as dichotomous electrophiles for the site-selective silylation via C−S bond cleavage has been achieved. The iron-catalyzed selective cleavage of C(aryl)−S bonds can occur in the presence of β-diketimine ligands, while the cleavage of C(alkyl)−S bonds can be achieved by t-BuONa without the use of any transition metal, resulting in the corresponding silylated products
