The bis(phosphino)amines (R2P)NH(PR′2) (R = R′ = isopropyl; R = R′ = phenyl; R = isopropyl, R′ = phenyl) react with ZnEt2 to form complexes with two different structural motifs, either the homoleptic monomeric P,P-chelates Zn[N(i-Pr2P)2]2 and Zn[N(i-Pr2P)(Ph2P)]2 or the heteroleptic dimeric Zn2N2P2 heterocycles {EtZn[N(PPh2)2]}2 and {EtZn[N(PPh2)(i-Pr2P)]}2. In two cases, CO2 reacts with these complexes to give adducts Zn[O2CP(i-Pr2)NP(i-Pr2)]2 and Zn[O2CP(i-Pr2)NPPh2][Ph2PN(i-Pr2P)]ZnEt2, similar to adducts formed from the reaction of CO2 with frustrated Lewis pairs (FLPs). In the other two cases, reaction with CO2 results in cleavage and rearrangement of the N-P bonds to give either N(PPh2)3 or Ph2P(iPr2P)NPPh2. The zinc complexes and their CO2 products were characterized with a combination of single crystal X-ray diffraction and multinuclear NMR spectroscopy.
