Structural isomers in the perkin reaction. II. Products of interaction of 4-bromophthalic anhydride with phenylacetic acids and some of their reactions
Isomeric bromobenzalphthalides of type 1 were obtained by condensation of 4-bromophthalic anhydride with phenylacetic acids. Isomeric benzalphthalimidines of type 6–11 were also prepared and some of their reactions discussed.
