摘要：

(Chemical Equation Presented) 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. © 2005 Wiley-VCH Verlag GmbH & Co. KGaA.
