Rcn react with lialh4
WebAcid chlorides can be reduced to alcohols by lithium aluminum hydride ( LiAlH4) and sodium borohydride ( NaBH4 ). In both reactions, there is an aldehyde intermediate formed and therefore, the reducing agent is used in excess to shift the reaction to completion. The mechanism of acid chloride reduction with LiAlH 4 is similar to the one of esters: WebAdvantages of using LiAlH 4 in reduction of aldehyde and ketone. LiAlH 4 do not reduce carbon–carbon double or triple bonds (with the exception of propargylic alcohols); All four …
