The parent benzophospholo[3,2-b]indole was prepared by the reaction of dichlorophenylphosphine with a dilithium intermediate, which was prepared in two steps from 2-ethynyl-N,N-dimethylaniline. Using the obtained benzophosphole-fused indole as a common starting material, simple modifications were carried out at the phosphorus center of the phosphole, synthesizing various functionalized analogs. The
通过二氯苯基膦与二锂中间体的反应制备母体苯并膦基[3,2-b]吲哚,该中间体是由2-乙炔基-N,N-二甲基苯胺分两步制备的。使用获得的苯并磷腈稠合的吲哚作为常见的起始原料,在磷的磷中心进行了简单的修饰,合成了各种官能化的类似物。对三价磷脂和氧化膦的X射线结构分析表明,稠合的四环部分是平面的。苯并磷腈稠合的吲哚,例如氧化膦,磷鎓盐和硼烷络合物,在二氯甲烷中表现出较强的光致发光(Φ= 67-75%)。
