✦ Synopsis

Three major DDD isomers, O,P'-DDD, m,p'-DDD and p,p'-DDD, 14C-labelled in the para-chlorophenyl ring, have been synthesized. The DDD products were obtained in isotopic yields ranging fran 42% to 58% and were of high specific activities; 31 mCi/mmol (0,~'-DDD; m,p'-DDD) and 19,8 mCi/mmol (p,p'-DDD). A minor amunt of %labelled o,m'-DDD was also isolated. 400 MHz data of the three major DDD isomers and o,m'-DDD were obtained.
