The synthesis and characterization of homo- and heteroleptic β-ketoesterate complexes of cobalt(II) and iron(III) by reaction of their nitrates and/or acetates with 2-(acetoacetoxy)ethylmethacrylate (HAAEMA) is described. The obtained complexes bear non-coordinated carbon-carbon double bonds and are therefore potential precursors of hybrid catalysts. The homoleptic Co(AAEMA)2 and Fe(AAEMA)3 complexes are obtained when Co(NO3)2 or Fe(NO3)3 reacts in alkaline medium with HAAEMA whereas the heteroleptic Co(AAEMA)(AcO) complex is formed starting from Co(AcO)2 and HAAEMA.

Abstract
The synthesis and characterization of homo- and heteroleptic β-ketoesterate complexes of cobalt(II) and iron(III) by reaction of their nitrates and/or acetates with 2-(acetoacetoxy)ethylmethacrylate (HAAEMA) is described. The obtained complexes bear non-coordinated carbon-carbon double bonds and are therefore potential precursors of hybrid catalysts. The homoleptic Co(AAEMA)2 and Fe(AAEMA)3 complexes are obtained when Co(NO3)2 or Fe(NO3)3 reacts in alkaline medium with HAAEMA whereas the heteroleptic Co(AAEMA)(AcO) complex is formed starting from Co(AcO)2 and HAAEMA.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
