Si-C bond activation in the reaction of first generation Grubbs' catalyst with alkynylsilanes - formation of [Cl(2){P(C(6)H(11))(3)}(2)Ru(=CHCH=CHPh)] anddisiloxanes.
The first generation Grubbs catalyst [Cl(2){P(C(6)H(11))(3)}(2)Ru=C(H)Ph] reacts efficiently with alkynylsilanes in the presence of water to give the styryl carbene complex [Cl(2){P(C(6)H(11))}(2) Ru=C(CH=CHPh)H] and disiloxane.
