Abstract

Triorganoarsenic(V) oximates of the type [R3As{ON = C(Me)Ar}(2)] (1) (R = Pr', Bu' Ar = C5H4N-2, C4H3O-2) are formed by the reactions of R-3,AsCl2, with the sodium salts of internally functionalized oximes in 1:2 molar ratio in anhydrous benzene. The redistribution products [R3As(X){ON = C(Me)Ar}] (2) (X = Cl, Br, OH) are obtained by treatment of 1 with equimolar R3AsX2. [Pr'As-3(OH){ON-C(Me)C5H4N-2}] may also be obtained by the reaction of Pr'3As(OH), with the corresponding oxime in 1:1 molar ratio. All of these complexes are characterized by IR and NMR (H-1 and C-13) spectroscopy and elemental analyses. Controlled hydrolysis of a representative monochloro-complex [Pr'As-3(Cl){ON=C(Me)C4H3O-2}] yields crystals of Pr'As-3(OH)Cl in which single crystal X-ray diffraction indicates that there is a distorted tetrahedral environment around arsenic.
