Final Report Abstract

The light-mediated [4+2]-cycloaddition between simple arenes and an arenophile (MTAD, N-methyl-1,2,4-triazolidinone) permits the dearomative functionalization of otherwise inert aromatic compounds. In-situ dihydroxylation and cleavage of the arenophile grants operationally easy access to highly functionalized cyclohexane derivatives. Benzene derivatives can be transformed to diversely functionalized cis-cyclohexa-3,5-diene-1,2-diol. Furthermore, mono and polycyclic aromatics can be converted into diamino-diols in a two-pot reaction sequence in good to excellent yields.
