Message definition (Zinc)
* The Frankland-Duppa Reaction in which an [[oxalate]] [[ester]] (ROCOCOOR) reacts with an [[alkyl halide]] R'X, zinc and [[hydrochloric acid]] to form α-hydroxycarboxylic esters RR'COHCOOR
* Organozincs have similar reactivity to [[Grignard reagent|Grignard reagents]] but are much less nucleophilic, and they are expensive and difficult to handle. Organozincs typically perform nucleophilic addition on electrophiles such as [[aldehydes]], which are then reduced to [[Alcohol (chemistry)|alcohols]]. Commercially available diorganozinc compounds include [[dimethylzinc]], [[diethylzinc]] and diphenylzinc. Like Grignard reagents, organozincs are commonly produced from [[organobromine compound|organobromine]] precursors.
