Abstract: The reaction of para-substituted thiophenols with Bi(NO3)3ċ5H2O and BiO(NO3)ċH2O was studied. The nitrate was more reactive than the subnitrate, and was a convenient bismuth compound for the preparation of trithiolates, Bi(SAr)3. Thiols having electron withdrawing groups seem to be more reactive than those with electron donating groups. The thiolato groups in Bi(SAr)3 can migrate to Bi(NO3)3ċ5H2O thus giving (ArS)2Bi(NO3), but the monothiolate product, ArS-Bi(NO3)2, decomposed evolving NO2. Bi(III) complexes with some aromatic thiols of probable biochemical interest are also described.
