内容記述 |
Irradiation of four substituted azobenzenes ( 1) in methanolic solution in the presence of titanium dioxide gave 1,2,4,5-tetraphenyl-1,2,4,5-tetraazacyclohexanes ( 3) in 28~62 % yields on addition of acetic acid under aerobic conditions, but di(1,2-diphenylhydrazinyl)methanes ( 4) and hydrazobenzenes ( 2) in moderate yields under nitrogen atmosphere and neutral conditions. Compounds 4 were labile to yield N-methoxymethylhydrazobenzenes ( 5) by nucleophilic attack of methanol in the dark, while to yield 3 by photocatalytic reactions under aerobic and acidic conditions. In addition, the similar photocatalytic reaction of hydrazobenzene also gave 3 and 4 under aerobic conditions. From these results, the photocatalytic reaction mechanism through a hydrazinyl radical was postulated. |
