Abstract
Abstract An aldol-type reaction of one of the carbaldehyde moieties of 2-hydroxy-5-methylbenzene-1,3-dicarbaldehyde (HL) takes place with ketones containing α-methyl and/or α-methylene groups through an in situ generated dicopper(II) complex, Cu 2 L 2 (ClO 4 ) 2 · 2H 2 O. The metal-free condensation products are 2-hydroxy-3-formyl-5-methyl-1-benzal ketones. No such reaction takes place with the mononuclear complex CuL 2 · H 2 O. The ligand (HL) itself undergoes uncontrolled self-condensation and polycondensation.
