ortho-Bromophenyl sec-alkyl/sec-alkenyl ketones, on reaction with sodium azide in the presence of copper salts, undergo sequential SNAr followed by Smalley cyclization to provide pseudo-indoxyl derivatives. Some of these pseudo-indoxyl derivatives exhibit interesting fluorescent properties and broad Stokes shifts.
ortho-溴苯基次级烷基/次级烯基酮与氮化钠在铜盐存在下反应,经过顺序的SNAr反应后进行Smalley环化,生成伪靛基衍生物。这些伪靛基衍生物中有些表现出有趣的荧光特性和较宽的斯托克斯位移。
