-
A process for preparing a silane of the formula I where R1 is --O--Y, n is an integer from 1 to 3, R2 is STR1 m is an integer from 1 to 3 and n+m=4, and Y and Z are each, independently of one another, unsubstituted or mono- or polyhalo-substituted C1 --C20 -alkyl, C2 --C20 -alkenyl, C2 --C20 -alkynyl and --(CH2)p --A, where p is an integer from 0 to 6 and A, which is unsubstituted or substituted by one or more C1 -C6 -alkyls, is a 3- to 20-membered hydrocarbon ring entails reacting a halosilicon compound of the formula II where X is fluorine, chlorine, bromine and iodine, with compounds of the formula III and IV, or with an anhydride of the formula V and the compound of the formula IV STR2 where R1 and R2, and Z have the above meanings, M is a metal of main group one and two.
