ChemInform Abstract
The ring-opening halosilation of five- and six-membered cyclic ethers using 1:2 mixtures of Et2NTms/alkyl halogenide (MeI, EtI, EtBr, AllylBr), or 1:1 mixtures of silane (Et3SiH, PhSi(Me)2H, Ph2Si(Me)H) and alkyl halogenide (MeI, AllylBr) in the presence of catalytic amount of palladium catalyst affords bifunctional halo(siloxy)alkanes, including halogenated silyl enol ethers.
