Addition of PPh 3 to the “lower‐order” cyanocuprate PhCuCNLi results in a significant increase in reactivity in 1,4‐Michael addition reactions. This is explained by a marked structural change in the cyanocuprate reagent, observed in both THF solution and the solid state, to give [Ph 2 Cu] − cuprate anions and a [Cu 2 Li 4 (CN) 4 (PPh 3 ) 4 (THF) 10 ] 2+ dication.
