Expanding the allyl analogy: accessing η³-P,B,P diphosphinoborane complexes of group 10.

ABSTRACT: Using the diphosphinoborane, (PPh₂)₂BMes (Mes = 2,4,6-Me₃C₆H₃), we report the first examples of η³-P,B,P-ligated complexes using Ni(0) and Pt(ii). Reaction of (PPh₂)₂BMes with Ni(COD)₂ or Pt(COD)Me₂ (COD = 1,5-cyclooctadiene) results in gradual COD displacement to give [η³-P,B,P-(PPh₂)₂BMes]Ni(COD) (3) or [η³-P,B,P-(PPh₂)₂BMes]Pt(CH₃)₂ (6). Complex 3 serves as a versatile Ni-containing synthon for the preparation of square planar or tetrahedral Ni(0) complexes. Notably, the M-B interaction in these systems is non-negligible - with coordination resulting in an upfield shift of ca. 80 ppm in the <
