Fe(OTf)2 was used to catalyze the insertionreaction of α-diazocarbonyls into S–H bonds at 40 °C. A wide range of α-thioesters were obtained in yields up to 96% within 24–48 h from their corresponding α-diazoesters. A variety of thiols were used for the unprecedented insertionreaction with an α-diazoketone, leading to yields up to 85% of α-thioketones.
The preparation of α-nitroepoxides from nitro olefins and hydrogen peroxide in the presence of base is reported and the behaviour of this new chemical species towards selected nucleophiles, acids and reducing agents is described. Mass spectral data is also presented.
