The application of phase transfer catalysis to the N-arylation of heterocyclic molecules is described ; N-arylbenzadiazepines are prepared according to this method. The phase transfer technique is compared to conventional procedures. The dynamic stereochemistry of the ring is evidenced by the change in 1Hnmr spectra line.
