reaction with NIS. Recently, Abe et al. have reported the generation of 1,1’-biazulene and 1,1’:6’,1”-terazulene derivatives by the reaction of ethyl 2-aminoazulene-1-carboxylate with NIS. They proposed a radical mechanism for the oxidative-coupling reaction quoted our previous reports. Several synthetic methodologies of 1,1'-biazulenes have been reported in the literatures. However, in most cases the methodologies
通过azuleno[1,2-b]噻吩与N-碘代琥珀酰亚胺反应制备新型噻吩稠合1,1'-二薁衍生物。通过CV、DPV和UV/Vis光谱对反应得到的新型1,1'-二薁衍生物的电子性质进行了表征。N-碘代琥珀酰亚胺(NIS)是有机化合物碘化的有效试剂之一。因此,在薁化学中,已经通过与 NIS 反应制备了几种 1-碘薁衍生物。最近,Abe 等人。已经报道了通过 2-aminoazulene-1-carboxylate 与 NIS 反应生成 1,1'-biazulene 和 1,1':6',1”-terazulene 衍生物。他们引用了我们之前的报道,提出了一种氧化偶联反应的激进机制。文献中报道了几种 1,1'-二薁烯的合成方法。然而,在大多数情况下,这些方法需要金属催化剂、高温反应和/或更长的反应时间。因此,Abe 等人 报道的反应。从无金属合成 1,1'-biazulene 衍生物的角度来看,它
