A Nitrogen Analogue of Deltic Acid
Weiss, Robert,Hertel, Marion
, p. 223 - 224 (1980)
The synthesis of dianilinophenyliminocyclopropene (1b), the first nitrogen analogue of deltic acid, has been achieved by a transamination reaction between tetrachlorocyclopropene (2) and trimethylsilylaniline (3), followed by deprotonation of the primary
