A green Keggin-type heteropoly-12-tungstophosphoric acid, (H3[PW12O40].12H2O) supported on graphitic carbon nitride g-C3N4 (HPW/g-C3N4-40), was developed for one-pot synthesis of quinoxaline derivatives from 1,2-diketone and 1,2-diamines. Use of green solvent, heterogeneous reaction condition, simple workup procedure, short reaction time and reusability of the catalyst are the advantages of this protocol.

负载在gC 3 N 4上的绿色固体酸催化剂12-钨磷酸H 3 [PW 12 O 40],用于合成喹喔啉

开发了一种绿色的Keggin型杂多12-钨磷酸(H 3 [PW 12 O 40 ] .12H 2 O),负载在石墨氮化碳gC 3 N 4(HPW / gC 3 N 4 -40)上。锅合成1,2-二酮和1,2-二胺喹喔啉衍生物。使用绿色溶剂,反应条件不均匀,后处理步骤简单,反应时间短和催化剂的可重复使用性是该方案的优点。
