The mononuclear niobium methylidyne [(PNP)(ArO)Nb≡CH] (1; PNP–= N[2-PiPr2-4-methylphenyl]2–, Ar = 2,6-iPr2C6H3) reacts with the isocyanate O═C═NtBu to form a mononuclear niobium oxo species with a rare example of an azaallenyl ligand, namely [(PNP)(ArO)Nb═O(CH═C═NtBu)] (2). When1is treated with the phosphaalkyne P≡CAd (Ad = 1-adamantyl), P≡C bond cleavage occurs to form a mononuclear complex where P–P coupling has occurred between the formal phosphaalkyne phosphorus atom and one phosphine arm from the PNP ligand, namely [(PNPP)(ArO)Nb(η2-AdCCH)] (3). Solid-state structural studies and isotopic labeling experiments confirm C–C bond formation of the methylidyne group as well as provide conclusive evidence for the oxo ligand in2being terminal and the fate of the phosphorus atom from P≡CAd in complex3. Computational studies have been applied to understand the pathway involving the P–P bond forming reaction of1and P≡CAd.
