摘要
Diphenyl selenide (k(q) = 2.5 x 10(9) mol(-1) dm(3) s(-1)) and selenoxide (2.5 x 10(8)) quenched the Type 11 reaction of butyrophenone through a charge-transfer process more efficiently than the corresponding sulfide (1.5 x 10(8)) and sulfoxide. The irradiation of 2-(benzylseleno)ethyl benzoylacetate gave bis[2-(benzoylacetoxy)ethyl] diselenide and 1,2-diphenylethane.
