The photolysis of ortho- and meta-tolylpentamethyldisilane (1 and 2) and 2,5- and 2,6-xylypentamethyldisilane (3 and 4 in the presence of isobutene and acetone as trapping agents has been studied. All reactions investigated, with the single exception of compound 4, afforded the 1:1 adducts derived from the silene as a result of a 1,3-silyl shift to the aryl ring with the trapping agents. The photolysis
在异丁烯和丙酮作为捕集剂的条件下,研究了邻甲苯基和间甲苯基五甲基二硅烷(1和2),2,5-和2,6-二戊五甲基二硅烷(3和4)的光解作用,所有反应均进行了研究。除了化合物4以外,由于捕获剂将1,3-甲硅烷基转移到芳环上,得到了由硅烯衍生的1:1加合物,在异丁烯或丙酮存在下1和3的光解得到了单加合物,但2分别得到5,6-双(甲硅烷基)取代的甲苯和3,4-双(甲硅烷基)取代的甲苯。的照射4中异丁烯的存在下,得到不挥发性产物,同时加入在甲醇的存在下它给methoxypentamethyldisilane和米二甲苯。
