Synthesis of benzonorbornadienes: regioselective benzyne formation.
J. Org. Chem. 66(9) , 2932-6, (2001) This report details the synthesis of several benzonorbornadienes by Diels--Alder cycloaddition of cyclopentadiene derivatives with substituted benzyne intermediates, which were generated by low-temperature metal--halogen exchange of halobenzenes. General cond... |

Azo group-assisted nucleophilic aromatic substitutions in haloarene derivatives: preparation of substituted 1-iodo-2,6-bispropylthiobenzenes.
J. Org. Chem. 69(6) , 1967-71, (2004) Aryldiazo substituents were used in nucleophilic aromatic substitution reactions of halogens. The Ph-N=N- group activates ortho fluorine atoms toward alkylthiolation under mild conditions. In contrast, the Me(2)N-C(6)H(4)-N=N- group has virtually no activatio... |
