A Cu(+)-CP based on the tetranuclear unit {[(HSQPA)2Cu4(bipy)4]·2H2O}n·2nH2O has been constructed through Cu(2+) salt, 2-(sulfonylquinlium-8-yloxy)phthalic acid (H3SQPA), and 4,4'-bipyridine (bipy). This Cu(+)-CP combined with 2,2,6,6-tetramethylpiperidine-1-oxyl as the cocatalyst is an effective catalyst for aerobic oxidation of alcohols and the synthesis of benzoxazoles and can be recycled at least four times without losing its catalytic activity.
