Synthesis and structural characterization of metal complexes based on pyrazole/imidazolium chlorides

A series of imidzoalium salt, L ? HCl, for the potentially bidentate pyrazole/N-heterocyclic carbene was synthesized. Reactions of a 2:1 mixture between L ? HCl bearing bulky N-substitution and Ag2O produced Ag(L)Cl, whereas a novel compound with unique stoichiometry AgL 2(AgCl)0.5Cl was produced from L ? HCl bearing N-methyl group under identical condition. Reactions of L ? HCl with PdCl2 produced zwitterionic PdIICl3L ? H. Selected structural determinations on L ? HCl, Ag(L)Cl, AgL 2(AgCl)0.5Cl, and PdIICl3L ? H revealed intriguing crystal chemistry in which the less-stable gauche rotamers were obtained exclusively. A preliminary application of the zwitterionic complexes, PdIICl3L ? H, in Heck coupling reaction of aryl bromide with n-butyl acrylate shows effective activity.
