Photocatalytic deracemisation of cobalt(<scp>iii</scp>) complexes with fourfold stereogenicity

The deracemisation of fourfold stereogenic cobalt(III) diketonates with a chiral photocatalyst is described. With only 0.5 mol% menthyl Ru(bpy)32+ photocatalyst, an enantiomeric enrichment of up to 88 : 12 e.r. was obtained for the major meridional diastereomers. Moreover, a distribution of configurationally stable diastereomers distinct from the thermodynamic ratio was observed upon reaching the photostationary
Aqueous-based crosslinkable coating composition comprising an aqueous dispersion of at least one polymer having epoxy-reactive functional groups, at least one polyepoxide compound, and at least one metal chelate complex epoxy-cure catalyst.
