BROMINATION OF 4-ARENESULFONAMIDOPHENOLS (OR 1-NAPHTHOLS) AND N-ARYLSULFONYL-1,4-BENZO(NAPHTHO)QUINON-4-IMINES

2,3,6-Tribromo-N-phenylsulfonyl-1,4-benzoquinon-4-imines are formed on bromination of 4-arenesulfonamidophenols and N-aryl-sulfonyl-1,4-benzoquinon-4-imines but 2-bromo-N-arylsulfonyl-1,4-naphthoquinon-4-imines are formed from 4-arenesulfonamido-1-naphthols and N-arylsulfonyl-1,4-naphthoquinon-4-imines.

CHLORINATION OF N-ARYLSULFONYL-1,4-AMINONAPHTHOLS AND N-ARYLSULFONYL-1,4-NAPHTHOQUINONE 4-IMINES

The final products from the chlorination of N-arylsulfonyl-1,4-aminonaphthols and N-arylsulfonyl-1,4-naphthoquinone 4-imines are 4-arylsulfonylimino-1-oxo-2,2,3,3,-tetrachloro-1,2,3,4-tetrahydronaphthalenes.
