Abstract
An X-ray analysis of 2,3-substituted-1,4-naphthoquinones has been perf ormed. On the basis of obtained data the structure factors causing the photoactivity of the investigated compounds has been determined. The study of photochemistry of these compounds in ethanol in common with q uantum-chemical calculations (INDO/S, MNDO) has made it possible to su ggest a mechanism of photoconversion for these compounds in solution c onnected with hydrogen atoms elimination and further synchronous cycle closure.
