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, Cu2L2(ClO4)2 · 2H2O. The metal-free condensation products are 2-hydroxy-3-formyl-5-methyl-1-benzal ketones. No such reaction takes place with the mononuclear complex CuL2 · H2O. The ligand (HL) itself undergoes uncontrolled self-condensation and polycondensation.
