Abstract
Mechanism of photoinitiated oxidation of yl-3,5-dicarbomethoxy-4-pheny l-1,4-dihydropyridine (I) in the presence of quinones has been studied by means of CIDNP method in polar solvents. 3,5-Dicarbomethoxy-4-phen yl-pyridine (II) has been identified to be the main reaction product. It has been found that the process involves the radical ions as well a s neutral radicals of dihydropyridine and quinone. Sigmatropic rearran gement (1-3 shift) has been suggested to occur in N-centered dihydropy ridine radicals. (C) 1997 Elsevier Science S.A.
