Synthesis of 8-Hydroselenoquinoline and Its Derivatives

The methods of synthesis 8-hydroselenoquinoline and its alkyl-, alkyloxy- and phenyl- derivatives have been discussed in the present work. The applicability of potassium selenocyanate and selenourea as the selenium-introducing reagent has been studied. The best results are obtained by the use of selenourea as the selenium-introducing agent. Using this reagent it seems to be possible to obtain some derivatives of 8-hydroselenoquinoline that cannot be synthesized by using potassium selenocyanate as selenium-introducing agent. The corresponding 8,8'-diquinolyldiselenide and methylselenoquinolines synthesized also. The obtained substances characterized by UV-spectra.
