Abstract
Abstract Tris(triorganostannyl) arsenites, (R3SnO)3As (R = Prn, Bun, Ph) and triorganostannyl alkylene arsenites, R3SnO AsOGO [R = Prn, Bun, Ph and G = -CH2- CH2-, -CH(CH3)CH2-, -CH(CH3)(CH3)CH-, -CH- (CH3)CH2CH2-, -C(CH3)2(CH3)2C-, -C(CH3)2- CH2(CH3)CH-] have been obtained for the first time as white solids or colourless viscous liquids by the condensation of bis(triorganotin) oxide with aresenous oxide and 2,2′-oxybis-1,3,2-dioxarsolanes and -arsenanes, respectively. While the latter are volatile under reduced pressure, the former disproportionate on heating into bis(triorganotin) oxides and triorganostannyl metarsenite. All these monomeric hydrolysable compounds have been characterised by elemental analysis, IR and NMR (1H, 13C, 119Sn) spectral data. The latter are consistent with configurational stability of the heterocyclic rings. A few cleavage and insertion reactions of these compounds have also been carried out to compare the reactivity of AsO and SnO linkages.
