Cooperative borane activation by tuning hemilability of different Os-κ²-<i>N</i>,<i>Se</i>-chelated complexes.

ABSTRACT: In an effort to investigate the cooperative activation of boranes, we have designed Os(iii) based paramagnetic mono- and bis-κ²-1,3-N,Se-chelated complexes, [Os(PPh₃)₂(κ²-N,Se-L)Cl₂], 1 and [Os(PPh₃)(κ²-N,Se-L)₂(L')], 2-3 (L = C₅H₄NSe; 2: L' = Cl and 3: L' = κ¹-Se-L). These complexes were synthesised by the thermolysis of [Os(PPh₃)₃Cl₂] with the potassium salt of 2-selenopyridine, which also afforded a diamagnetic species, [Os(PPh₃)₂(κ²-N,Se-L)₂], 4.
