The first solid-supported Cp′Co(I)-catalyst for the synthesis of pyridines
摘要:
We report on the successful modification of the air-stable CpCo(I)-complex [CpCo(trans-MeO2CCH=CHCO2Me){P(OEt)(3)}] (2) in order to enhance its recyclability by covalently linking this highly active catalyst for cycloaddition reactions on several solid supports. While the sol-gel-entrapped catalyst yielded no cycloaddition product, the silica-bound analogue led to the formation of the pyridine derivative, representing the first solid-supported Cp'Co(I)-complex to catalyze the cyclotrimerization of a diyne and a nitrile.
