Abstract

The reaction between Ph3SbBr2 and sodium salt of internally functionalized oximes in 1:2 molar ratio in refluxing anhydrous benzene afforded [Ph3Sb{ON=C(R)Ar}(2)] [R = CH3, Ar = C5H4N-2(1), C4H3S-2(2) C4H3O-2(3); R = H, Ar = C5H4N-2(4), C4H3S-2(5) and C4H3O-2(6)]. Treatment of (1) and (4) with 1 equiv. of Ph3SbBr2 yields the redistribution product [Ph3Sb(Br){ON=C(R)Ar}]. Controlled hydrolysis of (1) and (4) affords a species [Ph3Sb(OH){ON=C(R)Ar}]. All these complexes have been characterized by the elemental analyses, IR and NMR spectroscopic studies and in the case of I by single crystal X-ray diffraction studies. The structure of I features trigonal bipyramidal geometry around the antimony with the axial positions occupied by the two oxygen atoms of the oxime group [O(1)-Sb(1)-O(l)' 172.78(7)degrees] and equatorial positions by the phenyl groups.
