Intermediates of the cobalt carbonyl-catalyzed carbonylation of ortho-substituted benzyl halides were identified by IR, 1H- and 13C-NMR spectra. The mol. structures of the acyl-type derivs. 2-MeC6H4CH2C(O)Co(CO)3PPh3 and 2-PhC6H4CH2C(O)Co(CO)3PPh3 were detd. by X-ray crystallog. Structural features of these complexes are discussed.
