Synthesis of amino- and hydroxybiphenyls by radical chain reaction of arenediazonium salts
Radically shortened: In the propagation step of the title reaction, the cyclohexadienyl radical intermediate is oxidized by an arenediazonium ion to give the biaryl product (see scheme) while simultaneously a new aryl radical and nitrogen are formed. (Chemical Equation Presented).
