Afonin, M. Andriyankov, M. Nikitin] The action of natural light on 1-vinyl-2-pyridone and a series of its substituted compounds gave the corresponding photodimers with the retention of the vinyl group. The steric and electronic structure of the substances obtained was studied by the method of 1H and 13C NMR by comparison with the structure of the initial monomers. It was established that the stereoorientation of the vinyl group depends on the position of the substituent in the ring. Plenum Publishing Corporation, 1991 Afonin A.
