Abstract

The palladium (0)-catalyzed reaction of arenediazonium tetrafluoroborates with carbon monoxide and sodium carboxylates in acetonitrile at 25" C gave mixed acid anhydrides, ArCOOCOR (Ar= 3-MePh, 4Me-Ph, 2-MeO-Ph, 4-Br-Ph, 4-I-Ph, 3-N02-Ph, 4-N02-Ph, and Ph; R= H, Me, Et, t-Bu, and Ph), in good yields. Homoaromatic acid anhydrides,(ArCO) 20, were obtained by heating of ArCOOCOMe at 100-120 OC under vacuum. ArCOO-CO-t-Bu ...
