Descripción: | Aluminium borohydride reacts with triphenylphosphine to form initially a 1 : 1 adduct; subsequent addition of excess of ligand causes decomposition of this adduct, and results in cleavage of the AlH2B bridges. With ammonia the initial reaction product is a 1 : 2 adduct, Al(BH4)3,2NH3, but here excess of ligand cleaves the AlH2B bridges unsymmetrically, and the final product is best formulated as [Al(NH3)6]3+(BH4–)3. The relative strengths of the co-ordinate bond in a series of 1 : 1 adducts have been studied by displacement reactions which show NMe3 PMe3 > AsMe3 and Me2O > Me2S. The similarity in the nitrogen and phosphorus compounds is discussed with relevance to the formation of 1 : 2 adducts in these cases |
