Synthesis of Novel N- and S-Derivatives of 2-Naphthol - Promising Ligands for the Binuclear Copper Complexes
12 Pages Posted: 1 Apr 2020
N- And S-ligands for binuclear copper complexes were synthesized by the С-sp 2 -aminomethylation of 2-naphthol with N,N,N',N'-tetramethyldiaminomethane giving 1-dimethylaminomethyl-2-naphthol, which then reacted with 1,2-ethanedithiol to be converted to thiomethylated derivative. Direct thiomethylation of 2-naphthol and its acetate with formaldehyde and 1,2-ethanedithiol is nonselective, because the reaction involves both О- and С-sp 2 reaction centers of the substrate. Binuclear copper complexes with Cu-O-Cu-N- or Cu-Cl-Cu-S bonds were prepared.
