- 中文摘要: Photochemical reactions of 2- cyclopentylidenecyclopentanone with diisopropylmethylamine, diisopropylethylamine, dimethylaniline, triethylamine, isopropyldimethylamine and dimethylbutylamine in acetonitrile were studied. Besides the addition product, a novel 3+2 cycloaddition adduct 3a- hydroxytrispiro(octahydropentalene-1,1':2,1'':3,1'''- triscyclopentane)-2'''-one was isolated. The quantum yield and Stern-Volmer parameters with triplet quencher piperylene are reported. From these kinetic studies of mechanism photo-induced electron transfer and proton transfer is proposed for formation of the novel 3+2 cycloadduct of 2-cyclopentylidenecyclopentanone.
