Abstract
A process for dehydrogenating and methylating silanes. The process includes providing methyl chloride that is reacted with a silane selected from the group consisting of SiH4, H2SiMe2, H2SiMeCl, H3SiMe, H3SiCl and HSiMe2Cl, in the presence of at least one ammonium and/or phosphonium salt at a temperature in the range of 70-350° C.
