So far…….. ‘Simple Carbonyl compounds’ Conjugated Carbonyl compounds Most of chapters 19-23 19.13 and 23.10, 23.12
Week One’s Lectures A. Attack of nucleophile on slightly positive carbonyl carbon Carbonyl carbon as electrophile 19.4, 19.5, 19.6 21 19.8, 19.9, 19.11
Tuesday’s Lecture • New bond formed to the a carbon • a carbon as a nucleophile Behaves like alkene R1-X Behaves like nucleophile
R + 2 carbons carboxylic acid Malonic ester synthesis Acetoacetic ester synthesis R + 3 carbons ketone
C. Combination of A and B – remember formation of C-C bond Aldol Reaction Carbonyl carbon Can react with nucleophile 23.2 Can become nucleophile with base 23.3
Claisen Reaction Carbonyl carbon Can react with nucleophile 23.7 Can become nucleophile with base
