Certain dialkylbarbituric acids are subject to dealkylation in sulfuric acid. resonance in the barbituricacid ring and the relative stabilities of the dislodged carbonium ions. thiobarbituric acids rearrange in sulfuric acid to yield 2-alkylthio derivatives. acid ring is cleaved, whereas an allyl group may be readily converted to the 2-hydroxypropyl derivative. acid is transformed into the dilactone
