Methylenecyclopropanes and vinylidenecyclopropanes undergo ring-opening reactions with N-fluoroclibenzenesulfonimide (NFSI) upon heating at 60 degrees C in tetrahydrofuran to give the corresponding fluorinated derivatives 2 and 6 in good to excellent yields. A plausible reaction mechanism has been discussed on the basis of previous literature. (C) 2009 Elsevier Ltd. All rights reserved.
