Solid-state photolysis gives two products, one of which is produced as a racemate, while the other is formed in near-quantitative enantiomeric excess; the optical activity of the latter product probably results from intermolecular steric effects.}, isbn = {0108-2701}, url = {://A1994NH70800043}, author = {Chen, J.
