Relative Rate Constants for the Reactions of CF3OF with Olefins in Solution
The addition reactions of CF3OF to chloro fluoro olefins have been studied in solution at low temperature (-78, -105 deg C), and their relative rate constants have been determined using the kinetic approach of competition reactions.The reactivity and regio- and stereoselectivity are consistent with a free radical chain-propagating reaction in which the alkenes are attacked by the CF3O* radical generated by homolytic cleavage of the O-F bond in the CF3OF molecule.

Synthesis of Perfluoroethylmethylether by Direct Fluorination
The direct fluorination of trifluoromethylethers prepared from ethylene or fluorinated ethylenes with trifluoromethyl hypofluorite proceeded in excellent yield to obtain perfluoroethylmethylethers.
