For 10 points, identify these organometallic reagents that are named for a Frenchman.
The reaction of these compounds with phenylÂ·pyruvate was used to derive Cram's rule. Reactions of these compounds are initiated using a pinch of iodine or diÂ·bromoÂ·ethane. The palladium-catalyzed cross-coupling of these compounds is named for Kumada. Dioxane ("die"-OX-ayn) reacts with them to swing their solution equilibria toward their dimers. Alcohols can be lengthened by two carbons by converting them to these compounds and then reacting them with ethylene oxide. Two equivalents of these compounds are required to react with esters, whereas just one will nucleophilically attack a ketone to give a tertiary alcohol. These ultra-strong bases are synthesized by reacting alkyl halides with magnesium. For 10 points, identify these organometallic reagents that are named for a Frenchman.
