Chiral induction based on carbohydrate ligands in olefin platinum(0) complexes

A chiral N,N-ligand based on glucose is able to recognise selectively one enantioface of a prochiral olefin in a trigonal Pt environment. NMR and X-ray studies have been carried out aiming to disclose the factors, which govern this unexpected result. The selectivity originates from the ability of the ligand to create a chiral pocket of C2 symmetry, which is retained in both solution and solid state.
