Abstract
The thermal decomposition of the products of hydrogenation of the adducts obtained from arylfurans and dimethyl acetylenedicarboxylate leads to the formation of 2-aryl-3,4-bis(carbomethoxy)furans. The bromination of these compounds takes place in the 5 position of the furan ring; depending on the concentration of the nitric acid used, nitration leads to the formation of products of nitration in both the furan and the benzene rings.
