Intermediates of the cobalt carbonyl-catalysed carbonylation of ortho-substituted benzyl halides were identified by IR, H-1- and C-13-NMR spectra. The molecular structures of the acyl-type derivatives 2-MeC6H4CH2(O)Co(CO)(3)PPh3 and 2-PhC6R4CH2C(O)Co(CO)(3)PPh3 were determined by X-ray crystallography. Structural features of these complexes are discussed. (C) 2003 Elsevier Science B.V. All rights reserved.
