Carboxylic acid esters derived from N-hydroxypyridine-2-thione undergo efficient radical chain decarboxylation to the corresponding nor-alkane on treatment with either tri-n-butylstannane or t-butylmercaptan; in the absence of these hydrogen atom donors a smooth decarboxylative rearrangement giving noralkyl 2-pyridyl sulphides is observed.
在用三正丁基锡烷或叔丁基硫醇处理时,衍生自N-羟基吡啶-2-硫酮的羧酸酯进行有效的自由基链脱羧成相应的正构烷烃。在没有这些氢原子供体的情况下,观察到平滑的脱羧重排,给出了正烷基2-吡啶基硫化物。
