WebThe key difference between LiAlH4 and NaBH4 is that LiAlH4 can reduce esters, amides and carboxylic acids whereas NaBH4 cannot reduce them. Both LiAlH4 and NaBH4 are reducing agents. But LiAlH4 is a very strong reducing agent than NaBH4 because the Al-H bond in the LiAlH4 is weaker than the B-H bond in NaBH4. WebLiAlH4 Reaction and Mechanism. LiAlH 4 Mechanism. The commonly used reagent for the reduction of aldehydes and ketones are LiAlH 4 or NaBH 4.The reaction proceeds by …
