Reversible and Irreversible [2+2] Cycloaddition Reactions of Heteroallenes to a Gallaphosphene

[2+2] Cycloaddition reactions of gallaphosphene L(Cl)GaPGaL 1 (L=HC[C(Me)N(2,6‐i‐Pr(2)C(6)H(3))](2)) with carbodiimides [C(NR)(2); R=i‐Pr, Cy] and isocyanates [RNCO; R=Et, i‐Pr, Cy] yielded four‐membered metallaheterocycles LGa(Cl)P[μ‐C(X)NR]GaL (X=NR, R=i‐Pr 2, Cy 3; X=O, R=Et 4, i‐Pr 5, Cy 6).

description [2+2] Cycloaddition reactions of gallaphosphene L(Cl)GaPGaL 1 (L=HC[C(Me)N(2,6‐i‐Pr(2)C(6)H(3))](2)) with carbodiimides [C(NR)(2); R=i‐Pr, Cy] and isocyanates [RNCO; R=Et, i‐Pr, Cy] yielded four‐membered metallaheterocycles LGa(Cl)P[μ‐C(X)NR]GaL (X=NR, R=i‐Pr 2, Cy 3; X=O, R=Et 4, i‐Pr 5, Cy 6). Compounds 4–6 reversibly react with CO(2) via [2+2] cycloaddition at ambient temperature to the six‐membered metallaheterocycles LGa(Cl)P[μ‐C(O)O]‐μ‐C(O)N(R)GaL (R=Et 7, i‐Pr 8, Cy 9). Compounds 2–9 were characterized by IR and heteronuclear ((1)H, (13)C{(1)H}, (31)P{(1)H}) NMR spectroscopy and elemental analysis, while quantum chemical calculations provided a deeper understanding on the energetics of the reactions.
