在胺存在下,3,7-二硝基二苯并溴五环硫酸氢盐与二甲基亚砜反应生成2-溴-4,4’-二硝基-3’-二甲基锍-2’-联苯酚内盐(3).3的X射线晶体结构分析数据表明其分子具有内盐结构但酚氧负离子的负电荷是部分离域的,分子内两苯环所成的两面角为117.3°.3在熔解时发生重排及热分解分别生成2-溴-2’-甲氧基-3’-甲硫基-4,4’-二硝基联苯(6)及3,7-二硝基-4-甲硫基-二苯并呋喃(7).3与盐酸反应生成相应的锍盐(8).
In the presence of an amine, 3,7-dinitrodibenzothiopentacycles and bisulfite react with dimethyl sulfoxide to form 2-bromo-4,4’-dinitro-3’-dimethylsulfonium- 2-Biphenol inner salt (3) .3 X-ray crystal structure analysis data show that the molecule has an inner salt structure but the negative charge of phenolic oxygen anion is partially delocalized, the dipole angle formed by the two benzene rings in the molecule is 117.3 ° .3 rearrangement and thermal decomposition occurred during melting to generate 2-bromo-2’-methoxy-3’-methylthio-4,4’-dinitrobiphenyl (6) and 3,7 - Dinitro-4-methylthio-dibenzofuran (7) .3 Reacts with hydrochloric acid to form the corresponding sulfonium salt (8).
