Laser-photolysis studies have been carried out on a solution of 9-diazo-10,10-dimethyl-10-sila-9(10H)-anthracene in cyclohexane. In aerated solutions, the triplet 10,10-dimethyl-10-silaanthracen-9(10H)-ylidene was quenched with oxygen (kq=2×109 M−1s−1) to give a characteristic absorption (λmax at 425 nm) due to the corresponding carbonyl oxide.
对 9-重氮-10,10-二甲基-10-sila-9(10H)-蒽的环己烷溶液进行了激光光解研究。在充气溶液中,三重态 10,10-二甲基-10-硅蒽-9(10H)-亚基被氧气猝灭 (kq=2×109 M−1s−1),从而产生特征吸收(425 nm 处的 λmax)转化为相应的羰基氧化物。
