Rhodium-catalysed addition of arylboronic acids to oxabenzonorbornadienesElectronic supplementary information (ESI) available: experimental data. See http://www.rsc.org/suppdata/cc/b1/b108808d/

Abstract

The facile addition reaction of boronic acids to oxabenzonorbornadienes was achieved using a catalytic amount of a rhodium(I) complex having P(OEt)₃ ligands, affording cis-2-aryl-1,2-dihydro-1-naphthol stereoselectively, and in good yield without concomitant deboronation of the boronic acid.
