Fluorophenylantimony carboxylates. I. Synthesis and spectroscopic (UV, IR, 1H and 19F NMR) studies of some new monofluoro-and pentafluorophenylantimony(III and V) derivatives of 2-methoxybenzoic acid

Article abstract of DOI:10.1080/00945710009351808

A series of new mono-and pentafluorophenylantimony(III and V) arylcarboxylates of the type Ar_nSb(OOCC₆H₄OCH₃-2)_3-n and Ar₃Sb(OOCC₆H₄OCH₃-2)₂ (Ar = p-FC₆H₄-, m-FC₆H₄-and C₆F₅-, n =1 or 2) have been synthesized by the reaction of fluorophenylantimony (III or V) chlorides and the sodium salt of 2-methoxybenzoic acid in the presence of 15-crown-5 as phase transfer catalyst. A representative compound, namely trimethylantimony(V) bis(2-methoxybenzoate) has also been synthesized for the sake of spectral comparisons. The van't Hoff factor 'i' and molar conductance data of the compounds revealed them to be monomeric and non-conducting in nature. The compounds were characterised by the usual physicochemical techniques e.g., elemental analyses, UV, IR and NMR (¹H, ¹³C and ¹⁹F). Compound (III-VIII) are tentatively assigned as a trigonal bipyramidal structure in which the 2-methoxybenzoate acted as monodentate ligand.
