Carbonate esters of Formula (I): (R.sup.1)(R.sup.2)(R.sup.3)SiR.sup.4OC(O)OR.sup.4Si(R.sup.1)(R.sup.2)(R.sup.3) are prepared by reaction of a silyl-substituted alcohol of Formula (II): (R.sup.1)(R.sup.2)(R.sup.3)SiR.sup.4OH with an activated carbonyl compound of Formula (III): C(O)Z.sub.2 in the presence of a catalyst (e.g., an bicyclic amidine, a bicyclic guanidine, or a phosphazene) in an aprotic solvent. In Formulas (I) and (II) each of R.sup.1 and R.sup.2 independently is alkyl; R.sup.3 is alkyl or X.sup.1Si(R.sup.5)(R.sup.6)(R.sup.7); X.sup.1 is O or alkylene; R.sup.4 is alkylene; and each R.sup.5, R.sup.6, and R.sup.7 independently is alkyl. In Formula (III), Z is 1-N-imidazolyl or 1-N-succinimidyl. In some embodiments, the catalyst used in the methods described herein comprises at least one base selected from the group consisting of a bicyclic amidine and a bicyclic guanidine. The reaction proceeds readily under both bulk and continuous flow reactor conditions.
