And the article contained the following:
Palladium-catalyzed intermol. C-N bond-forming reactions between aryl halides and amides are described using 2-dialkylphosphino-2′-alkoxyl-1,1′-binaphthyl, which is both bulky and electron-rich, as the ligand. A variety of amides, including aliphatic and aromatic primary amides, lactams, and carbamates, e. g., I, II and III were viable substrates for the amidation, which exhibited good functional group compatibility. By tuning the substituents at the 2,2′-position of 1,1′-binaphthyl of the ligand, the palladium-catalyzed amidation of bulky aryl halides was realized and this coupling reaction was used to synthesize 2-amino-2′-methoxy-1,1′-binaphthyl in high yield. The experimental process involved the reaction of tert-Butyl (4-(trifluoromethyl)phenyl)carbamate(cas: 141940-37-6).Category: esters-buliding-blocks
