日期:2010.6.4
A catalytic synthetic approach for the synthesis of 2-quinolinone compounds through a Pd-catalyzed C(sp2)−H functionalization/intramolecularamidation sequence is described. The cyclization process efficiently proceeds in the presence of a catalytic amount of PdCl2 and Cu(OAc)2 under an O2 atmosphere, providing practical access to a range of variously substituted 4-aryl-2-quinolinones.

日期:2017.4.21
A Pd-catalyzed decarboxylative acylation of aromaticketones with α-oxocarboxylic acids was developed, and 1,2-diacylbenzenes were formed in up to 90% yield with excellent ortho-selectivity. This work demonstrates the first successful attempt to direct C–H acylation of aromaticketones without the need for prederivatization to imines. The acylation reaction was inhibited by radical scavengers such
