Investigation of the reaction of α-thioamides, α-esters and α-nitriles with NBS and NCS is described. The scope of this stereoselective oxidative transformation to the β-haloacrylamides, β-acrylates and β-acrylonitriles has been determined. A mechanistic rationale to explain the observed differences in reactivity between the amide, ester and nitrile series is proposed.
描述了α-硫代酰胺,α-酯和α-腈与NBS和NCS的反应的研究。已经确定了这种立体选择性氧化转化为β-卤代丙烯酰胺,β-丙烯酸酯和β-丙烯腈的范围。提出了一种机械原理来解释所观察到的酰胺,酯和腈系列之间的反应性差异。
