Fluoroalkylated N-heterocyclic carbene complexes of palladium have been syn
thesized from imidazolium salts and Pd(OAc)(2). The analogous carbene compl
exes bearing long alkyl chains have also been prepared. The formation of th
ese carbene complexes proceeds via an intermediate binuclear species, which
has been isolated. Complexes such as these may find applications in cataly
sis in supercritical CO2 (scCO(2)). (C) 2000 Elsevier Science S.A. All righ
