The reaction of perfluoroketene dithioacetal with lithium dienediolates of carboxylic acids proceeds at the W position probably through an addition to the pi system followed by elimination of the vinylic fluoride. The preparative value of this reaction depends strongly on the reaction and work-up conditions. The overall process lead to highly functionalised synthons containing a trifluoromethyl group.
