Products from the hydrocarbonylation of hex-1-ene or prop-2-en-1-ol using H2-CO or D2-CO in EtOH or EtOD have been analysed using 13C NMR techniques.Where there are up to four isotopomers in the products, analysis of β-shifted resonances in the 13C-<1H> NMR spectrum can give enough information for quantification of all isotopomers.Using prop-2-en-1-ol, D2-CO and EtOH, the 2-methylpropanol produced is a mixture of 16 different isotopomers.These can be individually quantified by analysis of the 13C-<1H, 2D> NMR spectrum.In particular, the resonance from the methyl C atom shows β and γ shifts, the latter being different for different types of γ-D atom.These analytical methods are shown to be superior to other possibilities including 1H NMR and mass spectrometry.
