概要

• 論文の詳細を見る

• The decomposition of [(4-amino-2-methyl-5-pyrimidinyl) methyl] dithiocarbamic acid (I) in alkaline solution was kinetically studied. The entropy of activation was largely negative compared with that of the corresponding 4-deamino compound (VIII). This result indicates the decomposition pathway should be I→VI→IV (Chart 1). The decomposition of the esters of I showing bell-shaped rate-pH profiles also follows a pathway similar to the above.
