The reaction of cyclopentadienyl substituted carbyne complexes of molybdenum and tungsten C5H5(CO)2-n(PMe3)n MCR (M Mo, W; R C6H5, C6H4CH3, CH3, n = 0, 1) (la-3c) with azides N3R′ (R′ CO2CH3, CH2CO2CH3) results in a [3 + 2]-cycloaddition to the electron-rich metal carbon triple bond, producing neutral 1-metalla-2,3,4-triazole complexes C5H5(CO)2-n(PMe3)nMC(R)NNNR′(M MO, W; R C6H5, C6H4CH3, CH3, n = 0, 1) (4a-7c) in high yields.The new compounds were identified by X-ray structure analysis (5b), elemental analyses, NMR, IR and mass spectra.
