Abstract The addition of halogens to N-arylsulfonyl-1, 4-benzoquinone imines, which exist in a solution as Z and E isomers, is controlled by the steric factor. ZE Isomerization strongly affects the stability of cyclohexene structures formed by halogenation of 1, 4-benzoquinone imines. The halogenation of N-arylsulfonyl-1, 4-benzoquinone imines was found to be accompanied by prototropic rearrangement.
