The reaction of diphenylacetylene with thermally generated cis- and trans-1,2-dimethyl-1,2-diphenyldisilene at 300 °C gave a mixture of the [2+2] cycloadducts in a stereoselective but not completely stereospecific manner. A stepwise radical mechanism is suggested.
二苯基乙炔与热生成的顺式和反式 1,2-二甲基-1,2-二苯基二硅烷在 300 °C 下反应,以立体选择性但不完全立体有择的方式得到 [2+2] 环加合物的混合物。提出了逐步激进的机制。
