phenyl-H-phosphinates or ethyl phenylpropiolate, reactive groups (phosphinic acid ester and carboxylic ester) could be integrated into the benzophosphole skeleton, which may be further functionalized towards various synthetic directions, therefore, fine-tuning the optical properties of the target molecules. The crystal structure of a benzo[b]phosphole oxide derivative was investigated by X-Ray diffraction, which
一种新的和实用的微波(MW)辅助方法是为快速和有效的氧化加成的仲膦氧化物或开发的烷基苯基ħ -phosphinates和乙炔。在氧化剂、反应时间、温度和起始材料的摩尔比方面优化反应。所开发的协议能够在温和条件下短反应时间内合成新型苯并[ b ]磷氧化物衍生物。通过使用特殊试剂,如烷基苯基-H-次膦酸或苯基丙酸乙酯,反应性基团(次膦酸酯和羧酸酯)可以整合到苯并磷骨架中,可以进一步向各种合成方向官能化,从而微调目标分子的光学性质。通过 X 射线衍射研究了苯并 [ b ] 磷氧化物衍生物的晶体结构,它提供了关于化合物及其在晶体中的分子相互作用的结构信息。
