A one-step, medium-scale synthesis of several novel dicyanomethyl and nitro substituted p-polyphenyls from 4,4’- or 4’’-diiodo-para-polyphenyls and from 4-iodo-4’- or 4’’-nitro-p-polyphenyls, respectively, and sodium malononitrile using a palladium catalyst is reported. A number of organic cation salts of these extended Ï-electron systems are likewise described.
