Organocopper reagents. See

For a chemical scale of the electron-transfer capability of organocopper reagents see a) Y. Chounan, T. 

For a review of the reactions of vinylic epoxides with organocopper reagents, see Marshall Chem. Rev. 1989, 89. 1503-1511. 

The products are useful substrates for conjugate addition of organocopper reagents (see this volume). 

For reactions involving stoichiometric conversion of organomagnesium compounds into organocopper reagents, see Chapter 16.
