Dehydration of the adducts 3 prepared by the 1, 2-addition between title com-pounds 2' with methyl, n-butyl, s-butyl Grignard reagents gives the corresponding conjugated ketene dithioacetals 4. The convertion from 2 to 4 provides a new and facile method for the prepa- ration of 4 a useful intermediate in organic synthesis.
