Abstract

Ammonium-and phosphoniumperfluorocyclobutane ylides 1 and 2, prepared from perfluorocyclobutene and tertiary amines or phosphines can be used as a masked fluoride anion source. These properties have been demonstrated in several reactions. Ylides 1 and 2 cleave C-Si or O-Si bonds, cause dimerisation of fluoroolefins or react with acid chlorides or activated aromatic compounds under halogen exchange.
