Abstract:
The interaction of a series of [Ni(P R1 2 N R2 2 ) 2 ] 2+ complexes 1 – 4 (where P R1 2 N R2 2 =1,5‐R 2 ‐3,7‐R 1 ‐1,5‐diaza‐3,7‐diphosphacyclooctane; R 1 = o‐ Py, Ph; R 2 =CHPh 2 , p‐ Tol) with H 2 is reversible yielding the products of heterolytic splitting of dihydrogen in the metal coordination sphere ‐ [NiH(P R1 2 N R2 2 )(P R1 2 N R2 2 H)] 2+ . Experiments conducted with parahydrogen allowed to see the signal at about −4 ppm corresponding to the metal‐bound H 2 in the nickel dihydrogen complex [Ni(η 2 −H 2 )(P Ph 2 N CHPh2 2 ) 2 ] 2+ ( 3‐H 2 ) – the short‐living non‐classical intermediate, which so far has been revealed only computationally.
