for E–E bond cleavage (where E = S, Se) at room temperature and gives satisfactory yield of the titled compounds. Molecular structure of bis[p-chlorophenyl(phenyl)methyl] diselenide (3) and diphenylmethylseleno-2-propene 7 has been established with the help of single crystal X-ray analysis. The compound (3) is triclinic and crystallizes into P1¯ space group, whereas the compound 7 is monoclinic with P21/C
借助于元素分析和各种光谱技术,已经合成并表征了许多新颖的,合成上重要的对称和不对称的二芳基甲基硫和硒化合物。该方法在室温下使用乙醇-DMF中的硼氢化钠进行E-E键裂解(其中E = S,Se),并得到满意的标题化合物收率。借助于单晶X射线分析已经建立了双[对-氯苯基(苯基)甲基]二硒化物(3)和二苯基甲基硒基-2-丙烯7的分子结构。化合物(3)是三斜晶系,并结晶成P1'空间群,而化合物7是单斜晶,具有P 2 1 / C空间组。
