Cyclopropylethylenes have been prepared by Wittig reactions, by coupling of dicyclopropylcarbene, and by dehydration of a suitably substituted ethanol. The scope and limitations of these preparations are discussed, particularly with regard to the synthetic application of the Wittig reaction to tetrasubstituted ethylenes.
