Theoretical insights into the [4+2]/retro [4+2] cycloaddition approach to the synthesis of biaryls and polycyclic aromatics
《Science China Chemistry》2013年第5期633-640,共8页LI XinYao XU JiaXi 
supported by the National Natural Science Foundation of China (21172017, 20972013 and 20772005);the specialized Research Fund for the Doctoral Program of Higher Education, Ministry of Education of China (20110010110011);"CHEMCLOUD COMPUTING " of Beijing University of Chemical Technology
A domino [4+2]/retro [4+2] cycloaddition process of cyclohexadienes with arylethynes or benzyne providing access to biaryls and polycyclic aromatics has been studied theoretically using density functional theory calcu...
