Abstract
Diborylated compounds are obtained by means of CpCo-mediated cocyclization of alkynyl(pinacol)boronic esters to alkenes followed by oxidative demetalation (see scheme). This strategy for the rapid and efficient construction of highly functionalized 1,3-cyclohexadienes and arenes is compatible with various substrates.
