Ketones and Aldehydes - Rutgers University

To stop the reaction at the ketone stage, a weaker organometallic reagent is required - a lithium dialkylcuprate fits the bill. The lithium dialkyl cuprate is produced by the reaction of two equivalents of the organolithium reagent with copper (I) iodide. 2 R-Li + CuI R 2 CuLi + LiI E.g.
