The invention relates to organosilicon compounds of the general formula Q-[S-G-Si(-O-CX1X2-CX1X3-)3N]. The organosilicon compounds are prepared by reacting at least one organosilicon compound of the general formula X10S-G-Si(-O-CX1X2-CX1X3-)3N and an organic or inorganic acid anhydride, an organic or inorganic acid halide or organic or inorganic ester. The organosilicon compounds are prepared by subjecting a compound of the general formula Q(-SH) to an addition reaction with at least one organosilicon compound containing double bonds and of the general formula CX1X2=CX2-G1-Si(O-CX1X2-CX1X3)3N. The organosilicon compounds are prepared by reacting at least one compound of the general formula Q(-S-X10) with a compound of the general formula halogen-G-Si (O-CX1X2-CX1X3)3N. The organosilicon compounds are prepared by reacting silanes of the general formulae Q-[S-G-Si(alkoxy)3], (alkoxy)3Si-G-S-C(=O)-Z-C(=O)-S-G-Si (alkoxy)3, (alkoxy)3Si-G-S-C(=S)-Z-C(=S)-S-G-Si(alkoxy)3 or (alkoxy) 3Si-G-S-C (=NR) -Z-C (=NR) -S-G-Si (alkoxy) 3 with compounds of the general formula (HO-CX1X2-CX1X3-)3N with elimination of (alkoxy)-H and separating (alkoxy)-H from the reaction mixture. The organosilicon compounds can be used in rubber mixtures.
