The synthesis and structural characterization of a N-heterocyclic carbene-substituted palladacycle

Abstract

Reaction of {[Pd(dmba)(mu-Cl)](2)} (dmba=(CH3)(2)NCH2C6H4) with ail ill situ generated N-heterocyclic carbene (NHC=1,3-dimesitylimidazolidin-2-ylidene) afforded crystals containing [chloro-(1,3-dimesitylimidazolidin-2-ylidene)(N,N-dimethylaminobenzyl-C-1,N) palladium(II)] (VII). Molecular and crystal structures of the title compound have been determined by single crystal X-ray diffraction technique. Complex VII crystallizes in space group Pi, with a=13.685(3) angstrom, b = 13.590(2) angstrom, c - 16.229(3) angstrom, alpha = 87.162(13)degrees, beta=70.514(15)degrees, y=84.153(16)degrees, Z=4, D-Calcd=1.367g cm(-3). There are two independent molecules in the asymmetric unit.
