  • ِFormation of New C-C for Aldhydes and ketones

    ِFormation of New C-C for Aldhydes and ketones

    To understand this simple reaction try to convert Acetone into t-butyl alcohol. Organometalic nucleophile usage Examples of organometallic reagent: R-Li , Grignard reagent. As you see you can add what ever group you need R to the carbonyl by adding it to lithium which make it suitable nucleophile (HOMO) to attack carbonyl group (LUMO). Mechanism:…

    Addition of nucleophile to Aldehydes and Ketones

    Nucleophile is the molecule with one ore more lone pairs or have negative charge. Cyanide (CN−) is potent nucleophile that can attake carbonyl group forming cyanohydrin In cyanide carbon bears the negative charge which make it the HOMO suitable for attaking electrophile to revise nucleophile read this. About carbonyl which is electrophile E+ it has…
