“…Schiff base ligands and their complexes have been studied extensively with the aim of shedding light on various aspects of catalytic activity [1][2][3][4][5], magnetic, spectroscopic and anticancer properties [6][7][8][9][10][11] as well as the role of metal ions in biological systems [12][13][14]. The active sites of many metalloenzymes contain nickel and copper, and the transition metals play important roles in controlling the catalytic function [15][16][17][18].…”

Enantiomeric resolution of the rac-biminap ligand is achieved through fractional crystallization of four diastereoisomeric palladium complexes involving ortho-metallated enantiomerically pure (R)-dimethyl(1-naphthylethyl)amine as a chiral auxiliary. After decomplexation, the absolute configuration of (R)-biminap and (S)-biminap has been unambiguously attributed by single-crystal X-ray crystallography, and their stereochemical purity is confirmed by measurement of their optical rotation and by re-derivatization with the initial resolving chiral complex. Palladium complexes of biminap are shown to efficiently catalyze Tsuji-Trost allylic substitution of 3-acetoxy-1,3-diphenylpropene by sodium dimethyl malonate. In the asymmetric version using the enantiomerically pure (R)-biminap ligand, significant solvent and anion effects are evident, and an ee up to 90% is obtained.
