SUBSTITUTIONS OF COPPER(II) CARBOXYLATES WITH SCHIFF-BASES

Substitutions of anhydrous copper(II) acetate with higher carboxylic a cids in an equimolar ratio in refluxing toluene yield monosubstituted soluble derivatives, which undergo substitutions with Schiff bases (de rived from salicylaldehyde and aniline or p-chloroaniline) to give mix ed complexes of the general formula [Cu(OOCR)(SB)] (HSB = Schiff base and R = C13H27, C15H31, C17H35 and C21H43). The products have been cha racterized by elemental analyses, electrical conductance, magnetic mom ent and spectral (i.r. and electronic) data. Cryoscopic molecular weig ht determinations indicate that the derivatives are dimers. The comple xes are e.p.r. silent.
