10-Dicyanoanthracene-sensitized photo-oxygenation of 2,2-diaryl-3-(2,2-diarylvinyl)oxiranes 3 in acetonitrile did not afford the corresponding 1,2,4-trioxepines 4, but 1,2,4-trioxolanes 7. The structural assignment of 7 was reported, and the mechanism of the formation of 7 was proposed.
乙腈中的2,2-二芳基-3-(2,2-二芳基乙烯基)氧杂环戊烷3的9,10-二氰基蒽致敏的光氧合反应无法提供相应的1,2,4-三氧杂环丁烷4,但1,2,4 -三氧戊环酮7。报告了7的结构分配,并提出了7的形成机理。
