title: Selective iodinated dipyrrolyldiketone BF2 complexes as potential building units for oligomeric systems.
abstract: Selective iodination at the alpha-pyrrole positions of dipyrrolyldiketone BF(2) complexes is a key procedure to afford mono- and bisiodinated derivatives as the starting materials of the coupling reactions for various utility molecules and covalently linked oligomer systems. Iodination can also be applied to the phenylene-bridging receptor dimer to obtain the derivatives selectively iodinated at the terminal alpha-pyrrole position(s).
