Silylation of substitued dioles by means of hexamethyldisilazane leads to 2,2,7,7-tetramethyl-3,6-dioxa-2,7-disilaoctane derivatives. Reactiions of these dioles with hexamethylcyclotrisilazane afford substituted 1,3-dioxa-2-silacyclopentanes.

O-silylation of OH groups of alcohols and phenols with hexamethyldisilazane (HMDS) was achieved in high-to-excellent yields using catalytic quantities of a SBA-15-supported cobalt(II) nanocatalyst (typically 0.5 mol-%) at room temperature and under solvent-free conditions. Furthermore, the heterogeneous catalyst showed an excellent durability and can be convenientlyreused by filtration for at least
