Organocopper chemistry is the study of the physical properties, reactions, and synthesis of organocopper compounds, which are organometallic compounds containing a carbon to copper chemical bond. They are reagents in organic chemistry.

The first organocopper compound, the explosive copper(I) acetylide Cu2C2 (Cu+[−C≡C−]Cu+), was synthesized by Rudolf Christian Böttger in 1859 by passing acetylene gas through a solution of copper(I) chloride in ammonia:

C2H2 + 2 [Cu(NH3)2]Cl → Cu2C2 + 2 NH4Cl + 2 NH3
