  Chemiluminescent reactions of ground and metastable states of the group IV A elements with halogens

  摘要：

  Earlier work on chemiluminescent beam-gas reactions of the ground states (3 PJ ) of Si, Ge, and Sn with F2 and of both ground and metastable states (1 D, 1 S) of Sn with Cl2 , Br2, and I2 is extended to include reactions of both ground and metastable states of Si, Ge, and Sn with F2 , Cl2 , Br2 , I2 , and ICl. Chemiluminescent products of metal halides and/or dihalides were observed in all of these reactions, although attempts to observe that in the similar reactions of Pb were unsuccessful. In ICl reactions with Si, Ge, and Sn, both monochloride and dichloride emission occurs, confirming the previously proposed mechanism for creating dihalide emission in Sn reactions with Br2 and I2 via a monohalide intermediate.

  二卤代甲硅烷基SiX 2与I 2或ICl在甲苯中的低温反应，生成二卤代碘代（甲基苯基）硅烷

  摘要：

  气态甲硅烷基SiX 2（X = F，Cl，Br或I）已在–90°C的条件下冷凝成I 2或ICl在甲苯中的溶液，从而得到了一系列新的式SiX 2 I（C 6的化合物）H 4 Me），证明了首先与SiO进行的亚甲硅烷基反应类型的一般性。所有产物都是邻位，间位和对位异构体的混合物，但在某些情况下，邻位异构体的比例非常高。由于使用I 2或ICl作为试剂可得到相同的碘硅烷衍生物，因此建议该反应涉及甲硅烷基离子SiX 2的亲电攻击我+，在竞技场上。
