WebJan 14, 2016 · We have developed a one-pot iron-catalysed sequential reaction of secondary amines with primary alcohols, trimethylsilyl cyanide and TBHP under mild reaction conditions to give the... WebHerein, we report the FeI₂-catalyzed reductive Strecker type reaction of formamides instead of aldehydes to produce amino acetonitriles. The challenging capture of carbinolamine intermediates by CN⁻ was achieved via Fe catalysis. This approach afforded better yields than the use of Ir- or Rh-catalysts.
