实验证明2,5-二溴-1,6-双(2,4,6-三甲苯)己二酮-[1,6]在硷性试剂(吡啶)存在时,不生成五碳环衍生物,也不生成季铵盐,但脱去溴化氢而生成1,6-双(2,4,6-三甲苯)己二烯-2,4-二酮-[1,6]。其结构由催化加氢生成1,6-双(2,4.6-三甲苯)己二酮-[1.6],加溴生成1.6-双(2,4.6-三甲苯)-2,3,4,5-四溴己二酮-[1,6],和由己二烯-2,4-二酰氯和1,3,5-三甲苯的合成而得到证明。
It has been experimentally demonstrated that 2,5-dibromo-1,6-bis (2,4,6-trimethylphenyl) hexanedione- [1,6] does not generate a five-carbon ring derivative in the presence of an alkaline reagent , No quaternary ammonium salt was formed, but hydrogen bromide was removed to produce 1,6-bis (2,4,6-trimethylphenyl) hexadiene-2,4-dione- [1,6]. Its structure is formed by catalytic hydrogenation of 1,6-bis (2,4,6-trimethylphenyl) hexanedione- [1.6] and bromine to give 1.6-bis (2,4,6-trimethylphenyl) -2,3,4,5 -hexabromohexadione- [1,6], as evidenced by the synthesis of hexadiene-2,4-diyl chloride and 1,3,5-trimethylbenzene.
