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
