通过一条新的路线合成了前所未有的2，2 ′-双（氮杂磷杂环戊二烯）。与NaH反应得到二价阴离子衍生物5，该衍生物容易转化为烷基化双（氮杂磷杂环戊二烯）或（Z）-P，P，N，N-顺式二氮杂二磷富瓦烯。该反应具有良好的区域选择性和立体选择性。用二氮杂二磷富瓦烯观察到相对强的荧光。X-射线晶体结构分析表明，二价阴离子配体5以桥连顺式方式与两个Na原子键合，这使得二氮二磷富瓦烯的合成具有高度的立体选择性。
The unprecedented 2,2′-bis(azaphosphindole) has been synthesized via a new route. Reaction with NaH afforded a dianion derivative5, which is easily transformed to alkylated bis(azaphosphindole) or (Z)-P,P,N,N-cisoiddiazadiphosphafulvalene. The reaction features good regioselectivity and high steroselectivity. Relatively strong fluorescence is observed with diazadiphosphafulvalenes. The X-ray crystal structure analysis showed that dianion ligand5is bonded to two Na atoms in a bridgingcis-fashion, which allows the synthesis of diazadiphosphafulvalene in a highly stereoselective approach.
