Trifluoromethyl Isocyanide, a Strong π‐Accepting Ligand – Pentacarbonyl(trifluoromethyl isocyanide)chromium and ‐tungsten Trifluoromethyl isocyanide ( 2 ) reacts with (CO) 5 M(THF) ( 1a,b;a : M = Cr, b : M = W) to form the new complexes (CF 3 NC)M(CO) 5 ( 3a, b ). From the vibrational spectra, which resemble those of the hexacarbonyl complexes, it is concluded, that the new ligand is a strong π‐acceptor.
