J. Ostermeier et al., SUBSTITUTION-REACTIONS ON 1-METALLA-1,1-D ICARBONYL-2,3,4-TRIAZOLE COMPLEXES OF MOLYBDENUM AND TUNGSTEN, Journal of organometallic chemistry, 472(1-2), 1994, pp. 30000008-30000012
In the presence of trimethylamine-N-oxide 3H-1,2,3,4-triazametalole co
mplexes of molybdenum and tungsten react with trimethylphosphine to gi
ve the corresponding substitution products in high yields. The new com
pounds where identified by X-ray structure analysis (4b), elemental an
alysis, NMR, IR and mass spectra
