摘      要：Surprisingly large amounts of the 1,4-adducts 5 are formed in the reaction of 3,3-diphenyl-1,2-propadienylidene (2)-generated from 1 under phase-transfer conditions-with the diene 3. Compounds 4 and 5 (overall yield 37%) are formed in a ratio of 78:22. The overall yield and product ratio in such reactions are dependent on both the carbene and the diene.
