reagents with methyl dithioacetate give dithioacetals (or hemidithioacetals) resulting from a carbophilic addition process. Reactions with various allylic organomagnesium compounds always involve an “inversion” of the allylic chain and direct carbophilic addition, rather than initial thiophilic addition followed by [2.3] sigmatropic shift. Three methods for the synthesis of β-unsaturated ketones are described
烯丙基,苄基,炔丙基和乙烯基格氏试剂与二硫代乙酸甲酯的反应,产生了由亲碳加成过程产生的二硫代乙缩醛(或半二硫代缩醛)。与各种烯丙基有机镁化合物的反应始终涉及烯丙基链的“反转”和直接的嗜碳性加成,而不是最初的亲硫性加成继之以[2.3]σ迁移。描述了三种合成β-不饱和酮的方法,这些方法显示了格氏试剂与二硫代酯反应的潜在合成用途。
