Abstract :
4-Substituted triazolinediones have been reacted with cyclopentadiene monomer, and the resultant cycloadductc (1a,b) treated with bromine in carbon tetrchloride. Contrary to expectation, addition of bromine to carbon-carbon double bond occurs via syn-addition in a stereospecific manner. The above triazolinediones have also been reacted with 1,3-cyclohexadiene and the resultand adducts (2a,b) subjected to bromination in carbon tetrachloride. In this case two products (trans and cis) are formed in a stereoselective manner.
