摘要:

AbstractIn presence of crown ether, 2‐alkoxy‐1,1‐dichlorocyclopropanes react witht‐BuOK/THF preferentiallyviaring opening to 2‐chloroalk‐2‐en‐1‐ones and alkynones or to chlorocyclopropenes. The latter may be intercepted with 1,3‐diphenylisobenzofuran, but in the absence of trapping agent, the rearrangement to vinylcarb
