Kinetic resolution of racemic tricarbonyl(2-Chloroanisole (cas 766-51-8))chromium via palladium-catalysed asymmetric alkoxycarbonylation

Add time:07/14/2019    Source:sciencedirect.com

Tricarbonyl(o-chloroanisole)chromium was treated with an alcohol and carbon monoxide in the presence of triethylamine and a chiral palladium catalyst to give (o-methoxybenzoate ester)Cr(CO)3 complexes in high selectivity with up to 30% ee. Starting tricarbonyl(o-chloroanisole)chromium was recovered in up to 39% ee. The Pd/PPFA catalytic system exhibited high reactivity and selectivity for the carbonylation reaction.
