Abstract

13C NMR spectroscopy was used for the unequivocal analysis of the mixture of products of RuCl2[P(C6H5)3]3‐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.
