FEATURES OF INFLUENCE OF HCl ON HYDROLYTIC COPOLYCONDENSATION OF BIFUNCTIONAL ORGANOCHLOROSILANES WITH TRIMETHYLCHLOROSILANE

The hydrogen chloride that is formed in the hydrolytic copolycondensation of R'RSiCl2 with Me3SiCl affects the composition of the reaction products only at cocentrations above 30-35percent, where it is responsible for splitting out the terminal trimethylsiloxy group.The stability of the terminal groups increases with increasing size of the substituents on the silicon atom in the R'RSiCl2.The total yield of Me3SiO(R'RSiO)mSiMe3 with m = 1-4 also increases with increasing size of the substituents on the silicon atom in the R'RSiCl2.The total yield of p with p = 3-5 increases with decreasing tendency of the R'RSiCl2 to form rings by hydrolytic polycondensation, and with increasing sensitivity of the terminal trimethylsiloxy group in the cocondensation products to the action of HCl and its activity with respect to the siloxane bond.

ZUR SYNTHESE VON SILOXANEN. IV. ACETOLYSE DER KONFIGURATIONSISOMERE DES 1-CHLOR-1,3,5-TRIMETHYL-3,5-BIS(TRIMETHYLSILOXY)CYCLOTRISILOXANS

The acetolysis reaction of 1-chloro-1,3,5-trimethyl-3,5-bis(trimethylsiloxy)cyclotrisiloxane was investigated using 29Si NMR spectroscopy.The three possible configurational isomers, formed in the synthesis, could not be separated.Taking into account the concentration of the three isomers in the mixture, the rate of their acetolysis reactions, the position and the order of the 29Si NMR signals of the chloro- and acetoxycyclotrisiloxane isomers from one set of 29Si NMR data information was obtained on the configuration of the isomers assigned to the NMR signals, the rate constants of the three isomers, and the stereochemistry of the acetolysis reaction.We found that the isomer present in the lowest concentration, showing the largest high field shift and the lowest reactivity has the all-cis configuration, and that the acetolysis reaction proceeds with retention of configuration.
