The radical decarboxylation reaction of N-alkoxyoxalyloxy-2-thiopyridone which was prepared by the reaction of alcohol, oxalyl chloride, and N-hydroxy-2-thiopyridone was studied both in the absence and presence of olefinic compounds. The same reactions with olefinic and acetylenic alcohols gave the corresponding lactone derivatives. On the other hand the unsymmetrical alkyl 2-pyridyl disulfides were obtained by the same reaction with aliphatic thiols.
对由醇、草酰氯和N-羟基-2-噻吩酮反应制备的N-烷氧基草酰氧基-2-噻吩酮的还原脱羧反应进行了研究,无论是在没有还是有烯烃化合物存在的情况下。同样,与烯醇和炔醇的反应得到了相应的内酯衍生物。另一方面,通过与脂肪族硫醇的相同反应得到了不对称的烷基-2-吡啶基二硫化物。
