A process for the production of 1-organylsilatranes and their carbofunctional derivatives of the general formula where R = --CH2 --CH2 -- or --CH(CH3)CH2- ; Z is a bivalent hydrocarbon radical; X = H, alkyl, aryl, F, Cl, Br, I, CF3, CN, NH2, SH, CNS, R1 M, (R2 O)2 P(O), R3 C(O)M, where R1 is alkyl, aryl, aralkyl or alkaryl; M = O or S; R2 is alkyl; and R3 is alkyl, aryl, RF (a fluorocarbon chain containing from 1 to 10 carbon atoms) or A-C6 H4 OCH2, where A is halogen, an alkyl group or an alkoxy group which comprises reacting triethanolamine or its derivatives of the general formula where R = --CH2-CH 2-- or --CH(CH3)CH2 --, with 1-organyltrialkoxysilanes of the general formula where R4 is alkyl; X = H, alkyl, aryl, I, Br, Cl, F, CF3, CN, NH2, SH, CNS, R1 M, (R2 O)2 P(O) or R3 C(O)M, where R1 is alkyl, aryl, aralkyl or alkaryl; M = O or S; R2 is alkyl; and R3 is alkyl, aryl, RF (a fluorocarbon chain containing from 1 to 10 carbon atoms) or A-C6 H4 OCH2, where A is halogen, an alkyl group or an alkoxy group, in the presence of a low-boiling polar organic solvent or a low-boiling polar organic solvent combined with an alkali catalyst, and subsequently recovering the desired product, and, the triethanolamine or its derivatives are initially admixed with said solvent, after which the 1-organyltrialkoxysilane is added to the reaction mixture.
