Why are terminal alkynes not used in catalysis?
As a result, terminal alkynes can not be metathesized under existing catalysis system with similar efficiency. In practice, 5 Å MS is used as butyne scavenger to shift the equilibrium to products. Alkyne metathesis can be used in ring-closing operations and RCAM stands for ring closing alkyne metathesis.
How does the metathesis of alkyne take place?
Alkyne metathesis is an organic reaction that entails the redistribution of alkyne chemical bonds. The reaction requires metal catalysts. Mechanistic studies show that the conversion proceeds via the intermediacy of metal alkylidyne complexes.

Which is a flexible reaction in ring closing alkyne metathesis?
Likewise, ring-closing alkyne metathesis (RCAM) is a particularly flexible reaction because the cyclic alkyne product can be partially reduced to yield the E or Z cyclic olefin with complete selectively.
