Isolation and X-ray structure determination of single invertomers of N-chloroamines

Abstract

syn- and anti-N-Chloro-derivatives of substituted 1,2,3,4-tetrahydro-1,4-iminonaphthalenes have been isolated as crystalline, configurationally stable compounds at ambient temperature; X-ray crystal structures and single crystal dissolution experiments at low temperature allow secure structural and n.m.r. correlations whilst at higher temperatures rapid inversion occurs in solution leading to a mixture of invertomers in each case.
