Article abstract of DOI:10.1016/S0040-4039(00)97684-6

Complete regioselectivity is observed in palladium(0) catalyzed allylic substitution reactions of 1-vinylcyclopropyl 3 and cyclopropylldeneethyl esters 6 with a series of soft carbon nucleophiles to give γ-cyclopropylidene-1,3-dicarbonyl and 1-carbonyl-2-sulfonyl compounds. Highly functionalized mathylenecyclopropanes are thus obtained in good to excellent yields from easily accessible 1-vinylcyclopropyl tosylates 3d.
