Arynes were found to insert into carbonâhalogen Ï-bonds of various acid halides, enabling acyl and halogen moieties to be introduced simultaneously into adjacent positions of aromatic rings.

Condensation of N-substituted lactams with carboxylic acid esters was studied. A wide range of substituted 2-acyl lactams with different ring sizes were synthesized. The structure of 2-acyl lactams (primarily, the ring size) was found to influence the keto-enol tautomerism.
Substituted benzoic acid compounds are disclosed, having the formula: ##STR1## The compounds find use as intermediates for the production of agricultural fungicides.
