Abstract Nucleophilic substitution of chlorine atoms in tetrachlorophthalonitrile by benzene- and alkanethiols in the presence of a base was studied at different reactant ratios. The substitution is characterized by complete regioselectivity: the chlorine atom in position 4 of tetrachlorophthalonitrile is replaced first; next follows replacement of the 5-chlorine atom. The reactions of tetrachlorophthalonitrile with nucleophiles at ratios of 1: 2 and 1: 4 lead to ...
