Notes: On a Diazadiboretidine as Four-Electron Donor against Chromium and TungstenThe iminoborane Bu—B = N-tBu (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 η4-[BuBN(tBu)]2 · M(CO)4 (4a, b) are formed from (OC)5M(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.
