Production of organosilanes, comprising an unsaturated, organic carbonyloxy group, comprises reacting a halo-organo-functional silicon compound with an unsaturated organic carboxylic salt in the presence of a phosphonium salt as phase transfer catalyst. Production of organosilanes of formula, (R<1>O)3-nR<2>nSi-X-OC(O)C(R<3>)=CR<3>2 (I), comprising an unsaturated, organic carbonyloxy group, comprises reacting a halo-organo-functional silicon compound of formula, (R<1>O)3-nR<2>nSi-X-Y (II) with an unsaturated organic carboxylic salt of formula, M<+>(<->OC(O)C(R<3>)=CR<3>2)0 (III) in the presence of a phosphonium salt as phase transfer catalyst. R<1> = monovalent 1-10C hydrocarbyl (optionally substituted and optionally comprising O in the chain; R<2> = monovalent, Si-C, 1-10C hydrocarbyl (optionally substituted and optionally comprising O in the chain, or sil(oxan)yl; X = divalent, 1-40C hydrocarbyl (optionally substituted and optionally comprising O in the chain; R<3> = H or monovalent 1-40C hydrocarbyl (optionally substituted and optionally comprising O in the chain; n = 0-3; Y = halo; M = an alkali(ne earth) metal atom; and o = 1 or 2, corresponding to the valency of M
