1,2,2,2-Tetrachloroethyl Carbamates: Versatile Intermediates for the Synthesis of N-Nitrosoureas
Barcelo, Gerard,Senet, Jean-Pierre,Sennyey, Gerard
, p. 1027 - 1029 (1987)
1,2,2,2-Tetrachloroethyl carbamates 3 were prepared by the reaction of 1,2,2,2-tetrachloroethyl carbonochloridate with amines.Carbamates 3 were then nitrosated and reacted with amines to yield N-nitrosoureas.
