Diboran(4)yl Pt II complexes : Selective oxidative addition of one BI bond in B 2 (NMe 2 ) 2 I 2 to [Pt(P i Pr 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 PtI bond lengths and the PtBr 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.
