Cl2 or ICl is the ClCO* radical which reacts subsequently with halogen or sulfur atoms or other matrix guests to give the corresponding carbonyl dihalide (OCCl2 and IC(O)Cl), syn-ClC(O)SCl or syn-ClC(O)SSCl. The analogous reaction with IBr affords syn-BrC(O)SBr, IC(O)Br, and syn-IC(O)SBr. The changes have been followed, the products characterized experimentally by IR measurements, and the spectra analyzed
在X轴和Y轴的性质上,约15 K的Ar矩阵中一起分离出的二卤素XY(= Cl2,ICl或IBr)与OCS的光解诱导反应会导致产生不同的光产物。 ,OCCl2,syn-ClC(O)SCl,syn-ClC(O)SSCl,IC(O)Cl,IC(O)Br和syn-BrC(O)SBr,syn-碘羰基亚磺酰基溴,syn-IC(O)因此,SBr首次被鉴定为涉及IBr的反应的光产物。与Cl2或ICl反应形成的第一个产物是ClCO *基团,该基团随后与卤素或硫原子或其他基质客体反应,生成相应的羰基二卤化物(OCCl2和IC(O)Cl),syn-ClC( O)SCl或syn-ClC(O)SSCl。与IBr的类似反应得到syn-BrC(O)SBr,IC(O)Br和syn-IC(O)SBr。进行了更改,
