TFEC

A solution of 2,2,2-trifluoroethanol (200 g, 2.0 mol) and pyridine (158 g, 2.0 mol) in dry diethyl ether (1 L) was treated with phosgene (99 g, 1.0 mol). The reaction mixture was stirred overnight and then filtered. The filtrate was distilled to give 199 g (88%) of bis(2,2,2-trifluoroethyl) carbonate.
