Abstract

The N-phosphinoamidinato digermynes [L [G with combining umlaut] e–eL] (L = tBu₂PNC(Ph)NAr, 4: Ar = 2,6-iPr₂C₆H₃, 5: Ar = Ph) underwent reversible CO₂ activation to form [LeOC(O)eL] (6: Ar = 2,6-iPr₂C₆H₃, 7: Ar = Ph). Compound 7 was further reacted with diphenylacetylene and hexafluorobenzene, which proceeded through compound 5 in the first step, to form CO₂, [L [G with combining umlaut] eC(Ph) = C(Ph) eL] (8), [LeF] (9) and [LeC₆F₅] (10), respectively.
