Alkyne Cross Metathesis Reaction

Tris(N-tert-butyl-3,5-dimethylanilino)molybdenum(III) (1) is a three-coordinate molybdenum(III) complex developed by Cummins et al. The said compound 1, reacts with dinitrogen to give the corresponding nitridomolybdenum complex. Fürstner et al. have reported alkyne metathesis reactions using 1 as a catalyst. Since these reactions proceed under mild conditions and the protocol permits the use of various functionalized alkynes, 1 has attracted much attention.
