Carboxylic acids can be prepared in moderate-to-high yields by treatment of diazonium fluoroborates with carbon monoxide and palladium acetate or copper(II) chloride. The mixed anhydride ArCOOCOMe is an intermediate that can be isolated. Other mixed anhydrides can be prepared by the use of other salts instead of sodium acetate." An arylpalladium compound is probably an intermediate." ...

The conversion of ArN2 salts into ArH takes place in hexamethyl-phosphoramide (by a long radical chain process), and also by the use of the naphthalene anion radical CioHs" in THF. Alternatively, deamination of ArNH2 can be carried out with Bu ONO in DMF. Unsymmetrical biaryls can be formed in a phase-transfer reaction between the diazonium fluoroborate (in an arene solvent) and KOAc complexed with 18-crown-6 polyether. ° Meerwein aryl-ation of fluorinated olefins with ArN2 and copper(ii) halides has been described, but an alternative procedure for the overall addition of ArHal to an alkene involves the use of ArNH2, Bu ONO, and copper(ii) halides in acetone or...
