Article abstract of DOI:10.1002/mrc.1270220909

13C NMR spectroscopy was used for the unequivocal analysis of the mixture of products of RuCl23-catalysed transfer deuteriation of benzylideneacetophenone by (a) DCOONa/H2O, (b) HCOONa/D2O and (c) DCOONa/D2O.Signal assignments in the 13C spectra were obtained mainly from the deuterium-induced 13C isotope shifts.The geminal 13C-2H shift of the β-carbon of deuteriated 1,3-diphenylpropan-1-one is almost twice that for the α-carbon.
