The previously reported Fe-catalyzed ortho C-H arylation of benzamides relied on bi- or tridentate amide groups and specific iron ligands and was sensitive to steric hindrance. By using new mixed titanates, our present protocol accommodates various weakly coordinating benzamides and tolerates high steric hindrance and sensitive functional groups only under the catalysis of FeCl3 and TMEDA. A wide range of privileged condensed ring compounds can thus be facilely accessed.

Phenyl radical intermediates formed by the reductive cleavage of the carbon-halogen bond in 2-halogeno-N-methyl-N-(1-naphthyl)benzamides undergo intramolecular substitution to give N-methyl-2-(1-naphthyl)benzamide, and no N-methylbenzophenanthridone is formed.Reduction of 2-halogeno-N-methyl-N-(2-naphthyl)benzamides gives N-methyl-2-(2-naphthyl)benzamide, N-methylbenzophenanthridone, and N-methylbenzophenanthridone.These results complete our comparison of this electrochemical reaction with related radical Pschorr cyclisations.Further reduction of these initial reaction products occurs that only qualitative conclusions can be drawn from the product yields.
