Abstract

The reaction of the bis(amino)cyclodiphosph(III)azane cis-{(tBuNH)2(PNtBu)2} with AlEt3, AlBrEt2, AlBr2Et, and AlBr3 was investigated. The less Lewis acidic compound AlEt3 forms the adduct cis-[(tBuNH)2(PNtBu){P(·AlEt3)NtBu}], in which the aluminum atom is exclusively coordinated to one phosphorus atom. No ethane elimination was observed. By using the more Lewis acidic compounds AlBr2Et and AlBr3 the N-coordinated complexes cis-[(tBuNH)(PNtBu)(tBuN·AlBr2Et){P(H)NtBu}] and cis-[(tBuNH)(PNtBu)(tBuN·AlBr3){P(H)NtBu}] were obtained, in which the aluminum atoms are N-coordinated by a tBuN=PH unit. Upon coordination of the aluminum compounds, a concomitant 1,2-H shift from the nitrogen atom onto the phosphorus atom within the cis-{(tBuNH)2(PNtBu)2} ligand was observed.
