On a Diazadiboretidine as Four‐Electron Donor against Chromium and Tungsten The iminoborane BuB = N‐ t Bu ( 1 ) is dimerized to the diazadiboretidine 2 by the catalytic action to tert ‐butyl isonitrile, being trimerized to the borazine 3 without a catalyst. The coordination compounds η 4 ‐[BuBN( t Bu)] 2 · M(CO) 4 ( 4a, b ) are formed from (OC) 5 M(THF) (M = Cr, W) and either 1 and 2 . The chromium atom in 4a is coordinated by four CO groups and the two nitrogen atoms of a non‐planar molecule 2 at the vertices and by the two boron atoms of 2 above two adjoining faces of a distorted octahedron.
