摘要

The title compound 15 was prepared as the first 1, 3-bis (diazo) ketone incorporated into a sevenmembered ring, and its photochemical pathways were investigated not only by product analysis study but also by using matrix isolation spectroscopy. Irradiation of 15 in alcoholic solvents gave 94 alkoxycarbony1) phenanthrene 16 as a main product, while similar irradiation in non-nucleophilic solvents provided diphenanthreno-syn-1, 5- ...
