(o-C6H4D)3Bi was prepared from BiCl3 and the Grignard reagent obtained from o-C6H4ClD (gained by solvolysis of the Grignard reagent from o-C6H4BrCl by CH3COOD). Redistribution of (o-C6H4D)3Bi and BiBr3 afforded (o-C6H4D)2-BiBr. It is demonstrated, that the paramagnetically shifted 1H NMR signal observed in phenyl derivatives of bismuth has to be assigned to ortho-protons.
