The sequential transformation of arynes into ortho-disubstituted arenes is achieved by a one-pot procedure using formamides and dialkylzincs. This reaction proceeded via a route involving the trapping reaction of the formal [2 + 2] cycloaddition adducts or quinone methides generated by the insertion of arynes into the C═Obond of amides.

The reaction of arynes, generated from ortho-(trimethylsilyl)aryl triflates, with the C=O bond of formamides gave salicylaldehyde derivatives via the formation of formal [2+2] adducts. The sequential transformation of arynes into ortho-disubstituted arenes, o-aminoalkylphenols or o-hydroxyalkylphenols, was achieved by one-pot procedure using dialkylzincs. (C) 2011 Elsevier Ltd.
