The reaction of benzyl phenyl ketazine with PCl3 in tetrahydrofuran affords 2-(1,2-diphenylvinyl)-4,5-diphenyl-2H-[1,2,3]diazaphosphole (1). An unusual 1,3-addition of methyllithium at the nitrogen (N-Li) and phosphorus (P-Me) atoms of diazaphosphole was discovered. The reduction peak potentials of diazaphosphole (1) and the starting ketazine were measured by cyclic voltammetry.
苯基苄基噻嗪与三氯化磷在四氢呋喃中的反应生成2-(1,2-二苯基乙烯基)-4,5-二苯基-2H-[1,2,3]二氮杂磷杂环戊烯(1)。在二氮杂磷杂环戊烯的氮原子(N-Li)和磷原子(P-Me)上发现了异常的1,3-甲基锂加成反应。通过循环伏安法测量了二氮杂磷杂环戊烯(1)和起始酮嗪的还原峰电位。
