Abstract

Abstract (Acetoxymethyl) silanes 2, 7 a–c, and 10 a–c with at least one alkoxy group, of the general formula (AcOCH 2) Si (OR) 3− n (CH 3) n (R: Me, Et, iPr; n= 0, 1, 2), were synthesized from the corresponding (chloromethyl) silanes 1, 6 a–c, and 9 a–c by treatment with potassium acetate under phase-transfer-catalysis conditions. These compounds were found to provide 2, 2, 5, 5-organo-substituted 1, 4-dioxa-2, 5-disilacyclohexanes 3, 8 a–c, ...
