Dihydrophenarsazine-based Arsenic-Thio Ethers ??? Preparation and Stabilization

L Arabuli1*, L Silaghi-Dumitrescu2, E Nikoleishvili1

10-chloro-5,10-dihydrophenarsazine (‘adamsite’) was used as starting materials to prepare arsenic-thio ethers: 10-benzothiazolylsulphyde-5,10-dihydrophenarsazine and 10-phenylsulphyde5,10-dihydrophenarsazine. The arsenic organic compounds were synthesized using potassium hydroxide and analyzed by various spectrometric instrumentations. The high toxic and high reactive 10-chloro-5,10-dihydrophenarsazine was converted into stable and low toxic compounds, which will be used as ligands for preparation of metal complexes and biological activity of new compounds will be studied.
