Versuchsvorschrift

A mixture of 1,1,1-trifluoro-2,2,2-trichloroethane and tert-butylvinyl ether in a 3:1 molar ratio is introduced to a jacketed photochemical reaction vessel. The mixture is irradiated using a medium-pressure mercury UV lamp so as to maintain the temperature of the mixture at about 35-45° C. for about 2 hours. The resultant reaction mixture is concentrated to remove volatiles and distilled to produce 3-chloro-4,4,4-trifluorobut-2-enal in a 60% yield.
