system is described. At low temperatures, the ratio of syn- and anti- N-chloroamines formed under conditions of kinetic control can be determined; this ratio is shown to be influenced substantially by variation in the electronic character of the aryl ring. At higher temperatures, inversion at nitrogen leads to different (thermodynamic) invertomerratios which also vary as a function of substitution

The configuration of chlorine determines the course of methanolysis of the title compounds; new structures are assigned to the reaction products and the rates of reaction of the anti-N-chloroamines are shown to vary according to the ability of the substituents in the benzo-ring to encourage benzo-participation.

etheno- (syn-chloro- series) or benzo- (anti-chloro- series) π-electrons. The high barriers to inversion at nitrogen together with some control over the ratio of invertomers allow observation of a different reaction pathway for each invertomer when reactions are performed at low temperatures; approaches which allow selection of the benzo- participation route (giving 6,7-benzo-derivatives of the 1-azabicyclo[3
