Intermediates of cobalt-catalysed PTC carbonylation of benzyl halides

Intermediates of the cobalt carbonyl-catalysed carbonylation of ortho-substituted benzyl halides were identified by IR, 1 H - and 13 C -NMR spectra. The molecular structures of the acyl-type derivatives 2-MeC 6H 4CH 2C(O)Co(CO) 3PPh 3 and 2-PhC 6H 4CH 2C(O)Co(CO) 3PPh 3 were determined by X-ray crys...

Summary:Intermediates of the cobalt carbonyl-catalysed carbonylation of ortho-substituted benzyl halides were identified by IR, 1 H - and 13 C -NMR spectra. The molecular structures of the acyl-type derivatives 2-MeC 6H 4CH 2C(O)Co(CO) 3PPh 3 and 2-PhC 6H 4CH 2C(O)Co(CO) 3PPh 3 were determined by X-ray crystallography.

Structural features of these complexes are discussed.
