A series of ferrocenyl triazole ligands have been synthesized and characterized, which proved to be effective for the Mn-catalyzed 1,6-conjugate addition/aromatization of para-quinone methides with good to high yields under mild conditions. This protocol provided an efficient and practical route to the synthetically interesting functionalized quinones, methines and their analogues.

A highly efficient catalytic system, CuSO4·5H2O/1-(4-methoxyphenyl)-3-phenylthiourea, for the copper(I)-catalyzed azide–alkyne cycloaddition reaction (CuAAC) was discovered. In the above catalytic system, substituted thiourea acts both as a reductant and a ligand. CuSO4·5H2O/1-(4-methoxyphenyl)-3-phenylthiourea is both an economical and efficient catalyst for the CuAAC reaction. In addition, the new catalytic system has advantageous features including mild and green reaction conditions, and broad substrate compatibility. A variety of 1,4-disubstituted 1,2,3-triazoles have been prepared with good to excellent yields with the CuSO4·5H2O/1-(4-methoxyphenyl)-3-phenylthiourea catalytic system in aqueous solution.
