Abstract
Esters of carbamic and carbonic acids are prepared by bringing a urea containing the group -CO-NH2 into reaction contact with a saturated monohydric alcohol and a source of boron trifluoride at a temperature above about 60 DEG C. Carbonic esters are also prepared using an alkyl or cycloalkyl carbamate in place of the urea. Sources of boron trifluoride include BF3 itself, monoamino boron trifluoride (NH3. BF3), ammonium flouborate, urea. BF3 complexes and complexes of BF3 and an oxygen containing aliphatic compound such as an ether, carboxylic ester or carboxylic acid. Excess alcohol is generally used as solvent. Elevated pressures may be used. The product may be recovered by filtering off the amino BF3 complex formed and distilling excess alcohol or by extracting with benzene. The reaction may be carried out in a continuous manner. Suitable ureas for starting materials include urea itself, alkyl urea, cycloalkyl ureas, aryl ureas and chloroaryl ureas. The alcohol may be an alkanol or cycloalkanol.
