Abstract The organomercurials RC(HgR')(CN)2 (R = Me, Ph; R1 = Ph, CH2Ph) have been obtained by the action of organomercury hydroxides R'HgOH or acetates R'HgOAc on substituted malonodinitriles RCH(CN)2- (Ph3PAu3O+BF4 reacts with the same nitriles to give organogold derivatives RC(AuPPh3)(CN)2. The study of the structures of organomercury and -gold compounds by1H,31P and199Hg NMR spectra as well as by IR spectra show that these compounds exist mainly in the C-form. The degenerated exchange reaction involving the cleavage of C-Hg bond takes place in the phenylmercury derivative of methylmalonodinitrile. Organomercury derivatives of substituted malonodinitriles are stable with respect to symmetrization in solution, in contrast to PhCH(HgPh)CN studied previously.
