Synthesis and Characterisation of Some New Organoantimony (V) Aryloxyacetates
نویسندگان
چکیده
A series of new tri and tetra-organoantimony (V) aryloxyacetates of the general formula R3Sb(OCOCH2OR’)2; and R4Sb(OCOCH2OR’) [where R = p-OCH3C6H4-, C6H5& R’ = p-CH3C6H4-, m-CH3C6H4-, o-CH3C6H4-, β-C10H7-, o-ClC6H4-], have been synthesised and characterised. These complexes are monomeric in benzene and non-electrolyte in acetonitrile. IR, NMR spectral data suggest the hepta-coordination with weak secondary interaction in between antimony and carbonyl oxygen of aryloxyacetate ligands. Keywords— Tri and tetra-organoantimony (V) aryloxyacetates, IR, H NMR, CNMR spectra, monomeric, non ionic, secondary interaction. —————————— ——————————

Graft copolymers of acrylamide on carboxymethyl cellulose (d.s 0.4-0.5) were prepared by the use of ceric ion, ceric ion/reductant molecule initiator systems in aqueous medium. The graft copolymers were characterized by IR spectroscopy. The extent of graft copolymerisation was measured in terms of grafted chains as a function of both ceric ion and ceric ion/reductant molecule concentrations. It...
