Abstract
A novel N-heterocyclic carbene-acetylamide ligand derived from
binaphthyl-2,2′-diamine (BINAM) and its dinuclear NHC-Pd(II)
complex as well as its corresponding complex bearing weakly coordinating
acetate counterions, have been successfully synthesized in good
yields. The dinuclear NHC-Pd(II) complex has been characterized
by X-ray diffraction. Moreover, we found that these complexes are
quite effective in Heck-Mizoroki reactions and give the
corresponding products in good to excellent yields.
Key words
N-heterocyclic carbene-acetylamide - dinuclear NHC-Pd(II)
complex - binaphthyl-2,2′-diamine - Heck-Mizoroki
