Abstract Trimethylsilylation of alcohols was achieved using 1, 1, 1, 3, 3, 3-hexamethyldisilazane (HMDS) as silylating agent, in the presence of polyvinylpolypyrrolidonium tribromide in acetonitrile at room temperature. Also a variety of alcohols were converted into alkyl formates by ethyl formate and a catalytic amount of polyvinylpolypyrrolidonium tribromide under solvent free conditions at room temperature.
