© 2018 American Chemical Society. 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==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). When 1 is 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(κ2-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 in 2 being terminal and the fate of the phosphorus atom from P=CAd in complex 3. Computational studies have been applied to understand the pathway involving the P-P bond forming reaction of 1 and P=CAd.
