The photocycloaddition of 1-naphthonitrile (1-NpCN) and 2,3-dimethyl-2-butene in cyclohexane or benzene gave cyclobutane 3 primarily,but that of 2-NpCN gave azetine 6 asthe major and cyclobutane 5 as the minor product in low conversion photolysis.

在低转化光解情况下，1-萘甲腈(1-NpCN)和2，3-二甲基丁烯-2在环已烷或苯中的光环加成反应主要得到环丁烷3，但2-NpCN主要得到氮杂环丁烯6和少量的环丁烷5，三氟醋酸量增加抑制1-NpCN和DMB的光环加成反应，表明TFA与基态及单激发态1-NpCN生成非光反应的复合物，它也淬灭(1-NpCN-DMB)激基复合物。

The photocycloaddn. of 1-naphthonitrile (1-NpCN) and 2,3-dimethyl-2-butene in cyclohexane or benzene gave cyclobutane I primarily, but that of 2-NpCN gave azetine II as the major and cyclobutane III as the minor product in low conversion photolysis. The photocycloaddn. of 1-NpCN with DMB is retarded by increasing amts. of trifluoroacetic acid which is shown to form non-photoreactive complexes with ground state as well as with singlet excited state 1-NpCN. It also quenches the *(1-NpCN-DMB) exciplex.
