Siloxacycles are synthesized in high yield and purity by reaction of acyloxymethyl (alkoxy) silanes in the presence of a catalyst which is a metal from groups 3 to 15 of the periodic table, or a compound thereof.

Silaoxacycles

Silanes containing an ester group are produced in high yield and purity by reacting a salt of a carboxylic acid with a silane containing a carboxylate substitutable leaving group following by distilling the product mixture to obtain a distillate containing the ester group containing silane product, wherein a solvent having a boiling point higher than the product is contained in the product mixture during at least a terminal portion of the distillation.
