The Friedel-Craftsacylation reaction between activated amides and arenes was carried out by employing [Pd(cinnamyl)Cl]2 and Cu(OTf)2 as catalysts. A range of N-phenyl-N-tosylbenzamides, which were substituted at the phenyl ring of the benzamide moiety, underwent reaction with various arenes, such as mesitylene, toluene, anisole, 4-tert-butylbenzene, o-xylene, m-xylene, and p-xylene, affording the

found to catalyze the coupling of acyl chlorides and aryl stannanes. The reaction involves aryl/chloride-bridged dinuclear gold(I) complexes as key intermediates, as substantiated by spectroscopic and crystallographic analyses. Similar to Pd(0)/Pd(II)-catalyzed Stille coupling with phosphine-borane ligands, the gold-catalyzed variant shows complete chemoselectivity for acyl chlorides over aryl iodides
膦-硼烷不会促进酰氯与金的氧化加成,但发现膦-硼烷金三氟甲酰亚胺络合物 [ i Pr 2 P( o -C 6 H 4 )BCy 2 ]AuNTf 2可以催化酰氯与金的偶联。芳基锡烷。该反应涉及芳基/氯桥联双核金 ( I ) 配合物作为关键中间体,经光谱和晶体学分析证实。与 Pd(0)/Pd( II ) 催化的 Stille 与膦-硼烷配体的偶联类似,金催化的变体对酰氯表现出相对于芳基碘化物和芳基溴化物的完全化学选择性,从而能够直接获得卤代芳基酮。
