controlled manner. Thus allylation of trisubstituted chlorosilanes (R3SiCl) afforded a variety of aryl, aralkyl, and alkenyl substituted allylsilanes. Dichlorosilanes (R2SiCl2) can either afford monoallylated silanes or diallylated silanes depending on the amount of allylsamarium bromide used. Similarly, trichlorosilanes (RSiCl3) can selectively afford mono-, di-, and tri-allylation products. Finally

valuable reagents in organosilicon chemistry. New difunctional silyl triflates, R2SiX(OTf) (X CH2CHCH2, CH2CH, OCH3; OTf OSO2CF3) have been prepared by substitution of allyl or phenyl groups at silicon by the trifluormethanesulfonyl group. The presence of the electron-withdrawing triflate group leads to a strong deactivation of the other substituents at the siliconatom, and therefore the displacement
