Abstract
A new hybrid catalyst composed of a vitamin B(12) derivative and a hyperbranched polymer (HBP) was synthesized and characterized by UV-vis and ESR spectroscopy as well as AFM. The B(12)-HBP showed good properties as a homogenous catalyst. The covalently-immobilized B(12) moieties were efficiently solvated and the cobalt centers were accessible for pyridine guests. The B(12)-HBP showed high reactivity to 2-phenethylbromide and increased selectivity for reductive dimerization in the presence of TiO(2) with UV light irradiation.Entities:
