Acetal protected 4-formylphenylbismuthane was prepared and used for arylation of trisubstituted hydrazines. Formylphenylhydrazines, obtained after removal of acetal group, were used in coupling reaction to give diols containing two substituted hydrazino moieties and the coupling of corresponding phenylimine derivatives gave corresponding diamines.
