The molybdenum complex [Mo{N(t-Bu)Ar1}3] (Ar1 = 3,5-Me2C6H3) in the presence of dichloromethane in toluene generates a catalyst that effects cross-metathesis reactions of functionalized alkynes (Scheme 53).[172] This catalyst also efficiently conducts homodimerization of aromatic alkynes to afford alkynes 102 as well as alkyne cross metathesis with aliphatic 1,2-disubstituted alkynes (e.g., alkynes 101 give 103 on reaction with 1,8-dichlorooct-4-yne, Scheme 53). Alkyne cross metathesis can also be performed with other symmetrical and nonsymmetrical 1,2-disubstituted functionalized aliphatic alkynes.
