Lewis acid activation of molybdenum nitrides for alkyne metathesis.
The substantial kinetic barrier to molybdenum nitride-alkyne metathesis is facilitated by precomplexation of the borane Lewis acid B(C(6)F(5))(3), providing convenient access to metathesis-active molybdenum alkylidynes. Spectroscopic and X-ray structural analysis suggest Mo≡N bond weakening upon borane complexation.
