Two drops of CH3COOH (glacial) and different acid halides (0.1mmol, 4a-i) were added and the reaction mixture which was stirred for 3-4 hours till completion of reaction confirmed via TLC.
The parent compound (3) was subjected to reaction with different acid halides (4a-i) in methanol in acidic conditions generated by glacial acetic acid.
The topics include electrophilic aromatic substitution, organometallic reagents, acid halides and anhydrides, aldol reactions, amines, and proton (1H) nuclear magnetic resonance.
