Chiral recognition in platinum complexes of 1,2-diphenyl-N,N′-bis[(2,4,6-trimethylphenyl)methyl]-1,2-diaminoethane. Stereoselective coordination of olefins and molecular structure of a trigonal bipyramidal adduct

Trigonal bipyramidal olefin-platinum complexes of the title chiral diamine (mestien) have been synthetized and their stereochemistry has been investigated by 1H and 13C NMR spectroscopy. The molecular structure of the complex PtClMe ((E)-ClCH=CHCl) (mestien) has been determined by X-ray diffraction analysis. The coordinated nitrogen atoms display a single configuration, and a high enantioface selectivity is observed in the coordination of prochiral olefins having a moderate lateral bulk. The selectivity can be correlated to the conformation adopted by the diamine ligand, which shows a remarkable similarity to those calculated for a proposed intermediate in the enantioselective dihydroxylation of olefins by osmium tetraoxide.
