A versatile method for the synthesis of carbamates from an 'in-situ' generated polymer-supported chloroformate resin is presented. BTC (bis-trichloromethyl carbonate) is used as phosgene equivalent to afford a supported chloroformate, which, by sequential 'one-pot' reaction with a variety of alcohols and amines, furnishes the corresponding carbamates in high yields and purities.
