organometallic reagents
... The alkyl group in alkylmetals is strongly basic. Carbanions are the conjugate bases of alkanes (estimated pKa’s of about 50), and as a result are extremely basic, much more so than amines or alkoxides. Because of their basicity, carbanions are extremely sensitive to moisture or other acidic functi ...

... The formation of carbon-carbon bonds is one of the most widely studied areas in organic synthesis. One class of carbon-carbon bond forming reactions involves the nucleophilic addition of vinyl or allyl organometallics to aldhydes, yielding allylic or homoallylic alcohols. The stereochemical unpredic ...
