Triphenylarsenic(V) and -antimony(V) derivatives of multidentate Schiff bases: synthesis,characterization, and antimicrobial activities
Abstract:Equimolar reactions of Ph n M(OPr i )2 (where M?=?As and Sb) with Schiff bases OHC6H4CH=N(R)OH] in benzene solution yield organoarsenic and -antimony derivatives, /></span> (where M?=?As and Sb; <i>n</i>?=?1 and 3; R?=?–CH<sub>2</sub>CH(CH<sub>3</sub>)–, –(CH<sub>2</sub>)<sub>3</sub>–, –(CH<sub>2</sub>)<sub>2</sub>–, and –C(CH<sub>3</sub>)<sub>2</sub>CH<sub>2</sub>–). All these derivatives have been characterized by elemental analyses and molecular weight measurements, and structures have been proposed on the basis of IR, NMR (<sup>1</sup>H and <sup>13</sup>C), and FAB-mass studies. Schiff bases and their corresponding organoantimony derivatives have been screened for antimicrobial activity against <i>Aspergillus flavus</i> (fungus) and <i>Escherichia coli</i> (bacteria).</td> </tr> <tr> <td align=
