Stereo-chemical analysis of racemization of a chiral bipyridine

Abstract

A chiral bipyridine derived from pinene was found to racemize in the presence of a copper(II) coordinating polymer. The possible racemization reason was examined by circular dichroism spectroscopy. Molecular protonation was determined as the key step of the conversion. Predicted co-crystal structure of a bipyridine and aromatic carboxylic acid mixture was confirmed by configuration roll-over of the pinene ring.
