Abstract |
Three new water-soluble copper(II) complexes [Cu(HL)(H2O)\(CH3)(2)NCHO\] (1), [Cu(H2L)(2)(im)(4)]center dot CH3OH (2) and [Cu(HL)(CH3OH)](2)(mu(2)-py) (3) were synthesized from copper(II) nitrate and sodium (Z)-2-(2-(1,3-dioxo-1-(phenylamino)butan-2-ylidene)hydrazinyl)benzene-su lfonate (NaH2L), in the absence (for 1) and presence of imidazole (im) (for 2) or pyrazine (py) (for 3), and fully characterized. The complexes 1-3 have been tested as stereoselective C-H activating catalysts for the model nitroaldol (Henry) condensation of nitroethane with various aldehydes in water. 1 was the most active catalyst affording 64-87\% yields with syn/anti diasteroselectivities up to 77:23.
