PHOTOCHEMICAL-TRANSFORMATIONS OF 1-ARGLCYANOMETHYL-9,10-ANTHRAQUINONES

Photochemical transformations of 1-arylcyanomethyl-9,10-anthraquinones were studied. it was established that under irradiation, the hydrogen atom of the substituted methyl group is transferred to a peri-quinoid oxygen atom to form the corresponding 9-hydroxy-1, 10-anthraquinone-1 -arylcyanomethides, Dark transformations of photoinduced quinone-methi des result from three competing parallel processes: intramolecular tra nsfer of the hydrogen atom, a reaction with a solvent (alcohol), and o xidation by dissolved oxygen. The kinetics of these reactions were stu died.
