Addition Reactions of Carbonyls Part 1
... Addition of hydride to a carbonyl group (reducing it to an alcohol) is also a very useful reaction. Hydride is H-; however, we cannot just add H- to C=O as H- is much more basic than nucleophilic (giving the enolate where possible). NaH and KH are great bases! So, how can we make an electron rich, n ...
