✦ Synopsis
A number of new chiral monomeric binaphthyl Schiff-base ligands H 2 L [where H 2 L = 2,2Ј-bis(3-R 1 -5-R 2 -2-hydroxybenzylideneamino)-1,1Ј-binaphthyl] and a series of chiral copper(II) complexes [CuL] were prepared in good or nearly quantitative yields. Some of the free ligands and the [CuL] complexes were structurally characterized by X-ray crystal-
