摘要:
The invention relates to a method for producing organosilanes of general formula I, [R(R)(R′O)Si—R″—]2Sm I by reaction of (halo-organo)alkoxysilanes of formula II, [R(R)(R′O)Si—R″-Hal II with a sulfuring reagent, selected from alkaline hydrogensulfide, alkaline sulfide Me2S, alkaline polysulfide Me2Sg and any combination thereof and optionally additionally with sulfur and/or with H2S in a solvent, the alkaline hydroxy content of all materials used being
