the amide (IIf) undergo both 1,2; and 1,4-additions. The unsubstituted amide (IId) gives predominantly 1,2-addition. The ketone (IVg) unlike ketones with one alkyl group undergoes 1,4-addition. The reaction of other Grignard reagents as well as phenyllithium with the same conjugated derivatives was also studied. Factors that determine 1,2 and 1,4-addition are discussed.
苯基溴化镁首先以1,2,然后再以1,4-方式加到腈(IIa)中,然后加到酯(IIb)中。酸(IIc)和酰胺(IIf)均经历1,2; 和1,4-加成 未取代的酰胺(IId)主要产生1,2-加成。与具有一个烷基的酮不同,该酮(IVg)进行1,4-加成。还研究了其他格氏试剂以及苯基锂与相同的共轭衍生物的反应。讨论了确定1,2和1,4-加成的因素。
