In the lithium aluminium hydride reduction water is usually added in a second step. The lithium, sodium, boron and aluminium end up as soluble inorganic salts at the end of either reaction. Note! LiAlH 4 and NaBH 4 are both capable of reducing aldehydes and ketones to the corresponding alcohol. Zaitsev’s rule is an empirical rule used to predict the major products of elimination reactions. It states that in an elimination reaction the major product is the more stable alkene with the more highly substituted double bond. This situation is illustrated by the 2-bromobutane and 2-bromo-2,3-dimethylbutane elimination examples given below.The mechanism. The first stage (the addition stage of the reaction) involves a nucleophilic attack on the fairly positive carbon atom by the lone pair on the nitrogen atom in the ethylamine. The second stage (the elimination stage) happens in two steps. In the first, the carbon-oxygen double bond reforms and a chloride ion is pushed off. In the lithium aluminium hydride reduction water is usually added in a second step. The lithium, sodium, boron and aluminium end up as soluble inorganic salts at the end of either reaction. Note!
