OXIDATION OF TRI(O-TOLYL)ANTIMONY BY TERT-BUTYL HYDROPEROXIDE. MOLECULAR STRUCTURES OF BIS[μ2-OXO- TRI(O-TOLYL)ANTIMONY] AND μ2-OXO-BIS[(TERT-BUTYLPEROXY)TRI(O-TOLYL)ANTIMONY]
Аннотация
Tri(o-tolyl)antimony oxidation by equimolar amount of tert-butyl hydroperoxide in diethylether led to the formation of bis[μ2-oxo-tri(o-tolyl)antimony] (1). At the molar ratio of reactants 1:2 or 1:4 μ2-oxo-bis[(tert-butylperoxy)tri(o-tolyl)antimony] (2) has been formed. According to the X-ray analysis data, antimony atoms are in the trigonal bipyramidal coordination in molecules 1 and 2. The bond lengths SbO vary within the ranges 1.937(2)2.078(2) Å (1) and 1.975(17)2.216(15) Å (2).
