抄録

Irradiation of 2,2-diphenyl-2H-1-benzopyran (DPBP) in the presence of a primary or a secondary amine gave an addition product. With a large excess of amine, the apparent quantum yield for product formation reached 0.5. This value corresponds to a minimal quantum yield for formation of DPBP colored ring-opened forms.
