WebSep 24, 2024 · General Reaction. Nucleophilic addition of a hydride anion (-:H) to an aldehyde or a ketone gives a tetrahedral alkoxide anion intermediate, which on protonation yields the corresponding alcohol.Aldehydes produce 1 o-alcohols and ketones produce 2 o-alcohols. Both LiAlH 4 and NaBH 4 are capable of reducing aldehydes and ketones to … WebApr 3, 2024 · Grignard compounds are popular reagents in organic synthesis for creating new carbon-carbon bonds. For example, when they are reacted with another halogenated compound R'−X' in the presence of a suitable catalyst, they typically yield R−R' and the magnesium halide MgXX' as a byproduct; and the latter is insoluble in the solvents …
