Description

1,4-Biradicals generated upon photo-irradiation of 2-aryl-3-{(thiophene-2-yl)methoxy}chromones produced angular tetracyclic products bearing the thienyl group. The dehydrogenation and ring contraction products were also observed depending upon the electron density on the 2-aryl ring. (author)
