The Synthesis of some phenylselenoglycollic acid derivates

In this study, some of the organic compounds of selenium (derivates of phenylselenoglycollic acids and selenoindoxyl) was synthesized and their structure was determined by spectroscopic methods. In the first part, the substituted phenylselenoglycollic acids was synthesized by means of diazonium salts in two steps. In the second part, substituted selenoindoxyls were prepared by means of cycliziation from the synthesized substituted phenylselenoglycollic acids. In the last step, selenoindoxyls was put into reaction with pyrolidine and then tried to synthesize 3-(l-pyrolidynl)benzo[b]selenophens. The first two steps was throwly completed. Although there was a reaction in the last step, the sufficient yield could not be obtained.
