Treatment of cis-1-iodo-3-chloro-1-propene derivatives, readily obtainable via trans addition of organometals to propargyl alcohols followed by iodinolysis and chlorination, with alkyllithiums, such as t-BuLi and n-BuLi, can proceed rapidly and cleanly even at −78°C to give in high yields cyclopropene derivatives, which undergo cis hydrometalation and carbometalation reactions more rapidly than the
