Abstract

From other works it is known that irradiation of benzfurazan (1) in methanol gives the carbaminacid-ester 4, whereas in benzene the azepinederivative 3 is obtained (Scheme 7). The compounds 5-8 (Scheme 2) have been proposed as intermediates. In our investigations we detected and characterized by means of UV.-and 1R.-spectroscopy the two species 5 and 8. Irradiation of 1 with 350 nm light at room temperature in a strongly polar solvent (eg ...
