Article abstract of DOI:10.1016/0022-328X(84)85165-7

At 150 deg C equilibria are established between chlorosilanes and alkyl esters according to the equation: MexSiCl4-x + RCOOR' <*> MexSi(O0.5)y(OOCR)z-yCl4-x-y-z + yRCOCl + zR'Cl.When x = 3, y = 0, z = 0.56; when x = 2, y = 0.26, z = 0.98.When x = 1, y = z = 0.56; when x = 0, y = z = 0.53.Lewis acid salts such as ZnCl2 or FeCl3 are effective catalysts for the reactions leading to mixtures of these compounds.
