Abstract

Co₂(CO)₈ has been reacted with but-2-yn-1,4-diol (BUD) and the reactivity of the resulting complex Co₂(CO) ₆(HOCH₂C≡CCH₂OH) (complex 1) is discussed. Complex 1 has been reacted with all the components used in the synthesis of sol-gel materials based on tetraethyl-orthosilicate (TEOS) with the aim at obtaining evidences for the processes occurring during the formation of inorganic-organometallic sol-gel materials containing BUD. Reaction pathways are discussed. BUD and complex 1 have also been reacted with 3-(triethoxysilyl) propyl isocyanate (TSI); the new ligand [(EtO)₃Si(CH ₂)₃NHC(- O)OCH₂C≡CCH₂OC(-O) NH(C H₂)₃Si(OEt)₃] (TB) and the complex Co ₂(CO)₆[(EtO)₃Si(CH₂) ₃NHC(-O)OCH₂C≡CCH₂OC(-O)NH(CH ₂)₃Si(OEt)₃] (11) have been obtained; these were characterized by means of spectroscopic techniques and mass spectrometry. Reactions of ligand TB and of complex 11 with TEOS have been performed. "Condensation" reactions of ligand TB (with TB) and of complex 11 (with complex 11) have also been attempted. Solid, amorphous materials were obtained: these were characterized by means of IR-Raman, SEM microscopy and XRD on powders.
