dibenzo[g,p]chrysene (DBC) is described, involving the synthesis of multi-hydroxyl DBC derivatives. Addition of 16 equiv Br2 to a suspension of DBC in CH2Cl2 enables to singly construct a 2,7,10,15-tetrabromo-DBC. A lithium-bromine exchange event leads the corresponding silyl molecule, and the following oxidation formed a tetra-hydroxyl derivative. Its isomeric tetra-hydroxyl DBC as well as more congested octa-hydroxyl
描述了区域选择性直接四溴化的二苯并[ g,对] ch(DBC),涉及多羟基DBC衍生物的合成。向DBC在CH 2 Cl 2中的悬浮液中添加16当量的Br 2能够单独构建2,7,10,15-四溴-DBC。锂-溴交换事件导致相应的甲硅烷基分子,随后的氧化形成四羟基衍生物。它的同分异构的四羟基DBC以及更拥挤的八羟基DBC也可以单独构建。这些简单明了的合成路线将为新的DBC材料提供一个通用的入口。
