摘要：

First chiral bidentate bis-carbene complex of Pd(II) prepared from a bis-imidazolium salt derived from (S) 2,2'-bromomethyl-1,1'-binaphthyl exists in both cis- and trans-square planar geometry. These and the corresponding trans-Ni(II) complexes are remarkably resistant to high temperature, air, water, and silica gel chromatography. The Pd complexes catalyze Heck reactions.
