摘要:
N-[N-Arylsulfonylbenz(acet)imidoyl]-3,5-dimethyl-1,4-benzoquinonimines react with alcohols to give the corresponding adducts at the activated C=N bond. The adducts lose alcohol molecule on heating to afford initial quinonimines. Hydrolysis of the title compounds leads to formation of the corresponding quinones and N-arylsulfonylamidines.
