Notes:
1,2-Di-tert-butyl-3-(diisopropylamino)-4-(dimethylamino)- 1,2,3,4-diphosphadiboretane (1) reacts with Fe2(CO)9 to give two isomeric tetracarbonyliron complexes 2, 3 with P-Fe bonds and a bis(tetracarbonyliron) complex 4. In contrast, 1 displaces the olefinic ligand from tetracarbonyl(η4-norbornadiene)metal (metal = Cr, Mo) to form the tetracarbonylmetal complexes 5 and 6 with a rearranged ligand molecule, i.e. a 1,3,2,4-diphosphadiboretane. This process is accompanied by a change of the tert-butyl groups from an anti orientation in 1 to a syn orientation in 5 as shown by X-ray crystallography.
