title: Evidence for a strong trans influence of the diboran(4)yl ligand.
abstract: Diboran(4)yl Pt(II) complexes: Selective oxidative addition of one B-I bond in B(2)(NMe(2))(2)I(2) to [Pt(PiPr(3))(2)] affords a trans-diboran(4)yl platinum(II) complex (see scheme; Ar(F) = 3,5-(CF(3))(2)C(6)H(3)). Comparison of its Pt-I bond lengths and the Pt-Br bond lengths of its bromine analogue with related species served to evaluate the trans influence of the ligand. The trans influence enabled facile halide abstraction to generate T-shaped 14-electron diboran(4)yl platinum(II) complexes.
