General description
1,4-Dimethoxy-2-butyne is a symmetrical aliphatic alkyne. Its reaction with Hg(OAc)2 (Mercury(II)acetate) has been investigated.
Application
1,4-Dimethoxy-2-butyne may be used in the preparation of alkyne complexes: decacarbonyl(μ3;-η2-verbar-1,4-dimethoxy-2-butyne)triiron and nonacarbonyl(μ3;-η2;-⊥-1,4-dimethoxy-3-butyne)triiron. It may also be used to synthesize benzonaphthosiline.

Rhodium-catalyzed intramolecular alkynylsilylation of alkynes is described. The reaction proceeds through syn-insertion by a cationic rhodium/triarylphosphine catalyst, representing the first alkynylsilylation of alkynes via the cleavage of a C(sp)-Si bond by transition-metal catalysis. A highly enantioselective variant is also described
