Thermolysis of 1,4-diphenyl-1,4-dioxa-2,3-benzopyrone (endoperoxide 1) in p-xylene solution generates chemiluminescence. Two intermediate products are formed from thermolysis of 1. The major product, trapped in 70% yield by added maleic anhydride, is 1,4-diphenyl-2,3-benzodioxin (o-xylylene peroxide 7). This peroxide becomes eventually o-dibenzoylbenzene 3 which is isolated from the reaction in 85% yield. The
摘要 : 1,4-diphenyl-1,4-dioxa-2,3-benzopyrone (endoperoxide 1) 在对二甲苯溶液中热解产生化学发光。两种中间产物由 1 的热解形成。主要产物是 1,4-二苯基-2,3-苯二恶英(邻二甲苯过氧化物 7),通过加入马来酸酐以 70% 的产率捕获。这种过氧化物最终变成邻二苯甲酰苯 3,它以 85% 的产率从反应中分离出来。第二个中间体未知。它形成于约。3% 的产率,显然最终成为苯基-(邻苯甲酰基)苯甲酸酯 (4) 反应的另一种分离产物。根据化学引发的电子交换发光 (CIEEL) 机制,化学发光源自 7 与添加的荧光激活剂或与次要中间体的相互作用。(作者)
