{Improved|Enhanced} syntheses of halogenated benzene-1,{2|two},{3|three},4-tetracarboxylic diimides
The preparation of halogenated benzene-1,{2|two},{3|three},4-tetracarboxylic diimide derivatives is {challenging|difficult} {because of|due to|as a result of} the possibility of competitive incorrect cyclizations and SNAr reactivity. {Here|Right here}, we demonstrate that the…
