COBALT PROPARGILATION OF THIOPHENES WITH HEXACARBONYLDICOBALT COMPLEXES OF PROPARGYL TYPE GLYCOLS
μ,η2-Hexacarbonyldicobalt complexes of alkynediols of propargyl type are cobalt propargylizing agents with two electrophylic reactive centers. Due to this fact they are promising reagents for preparing oligomeric structures containing aromatic nuclei and acetylenic groups. In this paper the possibilities of preparation the similar structures on the example of tiophenes are shown.
