During the last decade, methylenecyclopropanes (MCPs) have become readily available and found application in organic synthesis as versatile building blocks. Their chemical reactivity is due to a high level of ring strain, although they are surprisingly stable and easy to handle. 7., and Recently, we reported the convenient synthesis of homoallylic halides from methylenecyclopropanes and hydrogen halides. 8 This result, in turn, prompted us to investigate a possibility of the ...
