Poly(methimazolyl)borate complexes of platinum

Abstract

The reaction of iodotrimethylplatinum(IV) with 1 equiv of Na[HB(mt) 3] or Na[H2B(mt)2] (mt = methimazolyl) affords respectively the octahedral organometallic complexes [PtMe3{HB(mt) 3}] and [PtMe3-{H2B(mt)2}], the first isolated examples of poly(methimazolyl)borate complexes of platinum, which prove remarkably stable toward the reductive elimination of methane. The latter reacts further with [PtMe3I]4 to afford the novel, sulfur-bridged dinuclear complex [Me3-Pt{μ-H2B(mt) 2}PtMe3I].
