Page/Page column 6, (2012/01/15)
The invention relates to a method for producing silicon compounds (A) having hydrocarbon oxy-groups that have at least one unit of the general formula (1) HmSi (OR)n (OR′) oR″pX4-m-n-o-p (1) by conversion of silicon compounds (B) having at least one unit of the general formula (2) Hm+nSi(OR′)oR″pX4-m-n-o-p (2), having an alcohol of the general formula (3) ROH (3) in the presence of a catalyst (K) that is on a carrier material bonded metal selected from Ni, Pd, Pt, wherein per mol formed group OR, at maximum 1 liter of solvent is used and wherein R, R′, R″, X, m, n, o and p have the meanings listed in claim 1.
KINETICS OF THE ACID-CATALYSED SOLVOLYSIS OF SIX-MEMBERED CYCLOSILAZOXANES CONTAINING TWO SILAZANE BONDS

The solvolysis of N,N'-diphenyl-1,1,3,3,5,5-hexamethyl-1,3,5-trisila-2,4-diaza-6-oxacyclohexane (II) in methanol/water in the presence of an acetate buffer is a two-step, pseudo-first-order, process.Both steps are subject to general acid catalysis and their catalytic rate constants have been determined spectrophotometrically.The ring cleavage is faster than that of analogous cyclosilazoxanes containing a single silazane bond (I), but the catalytic mode, substituent effects, and the solvent isotope effect indicate a close mechanistic similarity for the solvolysis of I and II.
