## Abstract In presence of crown ether, 2‐alkoxy‐1,1‐dichlorocyclopropanes react with __t__‐BuOK/THF preferentially __via__ ring 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 a
