Molybdenum neopentylidyne complexes endowed with sterically demanding phenolates or branched fluorinated alkoxides are catalysts for alkyne metathesis. However, preparation of these catalysts is problematic by the standard
Schrock procedure. The trisalkoxide species 17 is active at room temperature.

Schrock type catalysts (complex 4). Another way to make complex 4 is via cleavage of internal alkyne by W(III) complex, such as 5. Complex 2, as well as
