Lavit, Kseniya published the artcileZooming in on the hydrated imidazoline ring expansion: Factors influencing the rate of N â?N’ aroyl migration in N-aroyl-N-(hetero)aryl ethylenediamines, Related Products of pyridine-derivatives, the publication is Tetrahedron Letters (2020), 61(42), 152423, database is CAplus.
The influence of electronic factors on the rates of N â?N’ aroyl migration in N-aroyl-N-(hetero)aryl ethylenediamines was examined Electron-withdrawing substituents on the aroyl group weakly accelerate the reaction (in linear correlation with the Hammett Ïp constants). Much stronger influence came from the nitrogen-bound aromatic group which gave a strong linear correlation with the Hammett Ï–p constants For electron-deficient heteroaromatics and nitroaroms., the migration was nearly instantaneous in basic medium. These findings will significantly impact the planning of mechanistically related transformations of N-(2-aminoethyl) lactams through the hydrated imidazoline ring expansion (HIRE) process.
