Rh(I)-catalyzed C6-selective C−H arylation of 2-pyridones with inexpensive, readily available, safe and structurally diverse aryl carboxylic acids with the aid of a pyridine directing group is developed. This decarbonylative arylation protocol features an easy-to-handle catalytic system, and is amenable to diversely substituted 2-pyridones and aryl carboxylic acids. It allows access to a wide range

A practical and efficient three step synthetic route to 2,3-diaryl (3H)-quinazolin-4-ones has been developed. The key step involves microwave-assisted condensation of an imidoylchloride with an aryl amine. This methodology affords the products cleanly and in high yields.

complexes of some polydentate ON, OO and ONO donors in the form of 2-methyl-3-substituted (3H)-quinazolin-4-ones have been synthesized and studied. The reactionbetween RuCl2(DMSO)4 and the uninegative bidentate ligands yielded complexes of the type Ru(DMSO)2(OO)2 (OO = MHQ, PHQ, MHEQ, MHPQ or MCMQ), displacing only two DMSO groups along with chlorides, whereas the neutral bidentate ligands gave
合成了一些多齿ON,OO和ONO供体的钌(II)配合物,它们以2-甲基-3-取代的(3 H)-喹唑啉-4-酮的形式存在,并且研究过。RuCl 2(DMSO)4与非负二齿配体之间的反应产生Ru(DMSO)2(OO)2类型的配合物(OO= MHQ,PHQ,MHEQ,MHPQ或MCMQ),仅取代了两个DMSO基团以及氯化物,而中性双齿配体给出RuCl 2(ON)2(ON= MAQ,PAQ,MANQ,PANQ,MAAQ,MAPQ,MPQ或PPQ),取代了所有DMSO基团。然而,具有O = N = O供体的单负性齿状配体(MHAQ)生成了钌(II)的双螯合物。
