Abstract
The synthesis of a new Costa-type ligand (H-2mdo), in which the propyl ene bridge has been replaced by a methylenedioxy bridge has been accom plished: two molecules of butanedione monoxime are coupled via a CH2 g roup by reaction with CH2Cl2 and 50% aqueous NaOH in the presence of a phase-transfer reagent. Dihalidocobalt and alkyl(halido)cobalt comple xes of the deprotonated ligand have been prepared and structurally cha racterized by NMR spectroscopy.
