Deuterium migration mechanism in chiral thiolactam formation by neutron diffraction analysis
The single-crystal neutron diffraction revealed that in the process of photo-induced beta-thiolactam formation from N,N-dibenzyl-1-cyclohexenecarbothioamide a deuterium atom bonded to the benzyl carbon atom is transferred to the intramolecular cyclohexene carbon to occupy the equatorial position of the produced cyclohexyl ring.
