Abstract The solvolysis of N-phenyl-1, 1, 3, 3, 5, 5, 7, 7-octamethyl-1, 3, 5, 7-tetrasila-2-aza- 4, 6, 8-trioxacyclooctane (I) and N, N′-diphenyl-1, 1, 3, 3, 5, 5, 7, 7-octamethyl-1, 3, 5, 7- tetrasila-2, 6-diaza-4, 8-dioxacyclooctane (II) in methanol/water in the presence of an acetate buffer is a pseudo-first-order process, subject to general acid-catalysis. The catalytic rate constants have been determined spectrophotometrically for the solvolysis of I. The ...
