Addition of Phthalimidonitrene to Isocyanates: A Facile Synthesis of Diazo Compounds
Kumar, P. Raja
, p. 678 - 679 (2007/10/02)
The aziridines (2a, b, c) obtained by the addition of phthalimidonitrene to aryl isocyanates (1a, b, c) undergo decarbonylation to give the diazo compounds (3a, b, c).Hydrazinolysis of (2a, b, c) gives the N-aminoaziridines (4a, b, c).
