Notizen:
α-Lactams have often been postulated as intermediates in numerous processes. The isolation of the first α-lactam, N-tert-butyl-3-phenylaziridinone, was accomplished in 1962. Since then, further N- and C-3-substituted α-lactams have been synthesized. Most of these very reactive compounds undergo easy thermal decomposition; remarkable is the relative stability of 1,3-di-tert-butylaziridinone, which does not start to decompose below 140°C. The α-lactam ring is opened by nucleophilic reagents. - The correlation of stability and substituents is discussed in the last section. An acyclic, planar or almost planar, charge-delocalized intermediate is suggested to explain the observed effects.
