Poly(methimazolyl)borate complexes of platinum

摘要

The reaction of iodotrimethylplatinum(l-V) 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 [Me-3-Pt{mu-H2B(mt)(2)}PtMe3I].
