A coupling reaction in organic chemistry is a general term for a variety of reactions where two fragments are joined together with the aid of a metal catalyst. ... Heterocouplings combine two different partners, such as in the Heck reaction of an alkene (RC=CH) and an alkyl halide (R'-X) to give a substituted alkene. It is a chemical reaction having a common intermediate in which energy is transfered from one side of the reaction to the other. Example - The formation of ATP is endergonic and is coupled to the dissipation of a proton gradient.
