Webcarbonylation of anilides to obtain N-acyl anthranilic acids.4d 35 In this regard, Orito et al, reported in 2004 the direct carbonylation with CO of aromatic C-H bonds in N-alkyl-ω-arylalkylamines using a Pd(OAc) 2 /Cu(OAc) 2 /air system in toluene solution at 120 ºC, to obtain benzolactams.4b,5 WebJan 15, 2024 · Summary. CO is a hallmark ligand of organometallic chemistry. The metal carbonyl complexes have been studied for a long time. The CO ligands bind tightly to metal center using a synergistic mechanism that involves σ−donation of the ligand lone pair to metal and followed by the π−back donation from a filled metal d orbital to a vacant σ ...
