mechanism of formation of phthalimide from phthalic anhydride
Phthalimide Phthalimide can be prepared by heating phthalic anhydride with aqueous ammonia giving 95â€“97% yield. Alternatively, it may be prepared by treating the anhydride with ammonium carbonate or urea. It can also be produced by ammoxidation of o-xylene.[2]
Friedel–Crafts reaction Reaction of chloroform with aromatic compounds using an aluminium chloride catalyst gives triarylmethanes, which are often brightly colored, as is the case in triarylmethane dyes. This is a bench test for aromatic compounds.[38]
