WebSeveral amides were obtained in high yields by an efficient method from the corresponding imines which are readily prepared from aldehydes. This procedure involves the oxidation of aldimines with m-CPBA and BF 3 ·OEt 2. In this reaction, the product is strongly influenced by the electron releasing capacity of the aromatic substituent (Ar). G.
WebMechanism of Aldol Condensation. Step-1: In reverse order, The hydroxide ion deprotonates the aldehyde. Step-2: Here Enolate ion 1 adds to the unreacted aldehyde. Step-3: Alkoxide ion 2 is protonated by water. Step-4: A small amount of aldol is converted into enolate ion (4) by hydroxide ion. WebAug 10, 2016 · The carbonate reacts with the alcohol to produce an alkoxide. Explanation: The equation for the Williamson synthesis is R-X + R1-O- → R-O-R1 +X- Since alkoxide ions are highly reactive, they are usually prepared immediately prior to the reaction or are generated on the spot.
