以市售三苯基膦间磺酸钠和四溴化碳为原料制备的固体络合物,可作为一种易于回收和重复使用的催化剂体系,用于2-萘酚与醛的一锅缩合反应,合成14-芳基(烷基)-14H-二苯并[a,j]并[a,j]并[a,j]杂菲衍生物,以及2-萘酚与醛和环1,3-二羰基化合物的一锅缩合反应,合成12-aryl(alkyl)-8,9,10,12-tetrahydrobenzo[a]xanthen-11-one衍生物。
A solid complex, readily prepared from commercially available sodium triphenylphosphine-m-sulfonate (TPPMS) and carbon tetrabromide, can be used as an easily recoverable and reusable catalyst system for one-pot condensation of 2-naphthol with aldehydes to construct 14-aryl(alkyl)-14H-dibenzo[a,j]xanthene derivatives and one-pot condensation of 2-naphthol with aldehydes and cyclic 1,3-dicarbonyl compounds to construct 12-aryl(alkyl)-8,9,10,12-tetrahydrobenzo[a]xanthen-11-one derivatives.
