Syntheses of Cyclic Triphenylantimony(V) Catecholates from Triphenylantimony, tert-Butyl Hydroperoxide, and Polyhydric Phenols
Cyclic triphenylantimony(V) catecholates are prepared by reactions of triphenylantimony with polyhydric phenols (pyrogallol, hydroxyhydroquinone, and quercetin) in the presence of tert-butyl hydroperoxide. Triphenylantimony reacts with polyhydric phenols selectively at the o-hydroxy groups to give the corresponding Sb(V) derivatives.
