A series of β-thio group substituted α-diazo carbonyl compounds have been prepared by nucleophilic substitution reactions of thiophenol, thionaphthol, or benzyl mercaptan with β-acetoxy-α-diazo carbonyl compounds. The diazo decomposition of these diazo carbonyl compounds with various transition metal catalysts, including Rh(II) carboxylates and Cu(I) and Cu(II) complexes, has been investigated. It
通过硫代苯酚,亚硫醇或苄基硫醇与β-乙酰氧基-α-重氮羰基化合物的亲核取代反应已经制备了一系列β-硫基取代的α-重氮羰基化合物。研究了这些重氮羰基化合物在各种过渡金属催化剂(包括羧酸Rh(II)和Cu(I)和Cu(II)配合物)上的重氮分解作用。发现这些化合物的重氮分解产生1,2-硫基迁移产物。在所有情况下均未观察到1,2-氢化物或1,2-芳基迁移产物。
