Carbanions are looked at with examples and how to stabilise through inductive and resonance effects. Enolate formation reaction is introduced and a look at different bases and how complete deprotonation can be. The stabilisation of enolates develops the topic before the α-halogenation by base or acid catalysed reactions. More enolate reactions are given. Alkylate aldehydes formation through enamines. Aldol reaction through acid and base conditions in either equilibrating and non-equilibrating c...

Most notes are types and structure drawn with chemdraw, some mechanism, and quite cheat sheet are shown in neat handwriting produced on ipad. Most reactions show detailed step-wise mechanism (with electron transfer arrows) Material covered are as shown below Carbonyl rearrangements: Schmidt, Beckmann, Curtius, Wolff Enols and Enolates: ketone deuteration, alpha-halogenations, alpha-alkylations, enamine alkylations, decarboxylation Aldol Reaction: general, condensation, Cross Aldol condensation, ...
