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.
