A Palladium-catalyzed three-component-coupling strategy for the differential vicinal diarylation of terminal 1,3-dienes
A palladium-catalyzed intermolecular vicinal diarylation of terminal 1,3-dienes using aryldiazonium tetrafluoroborates and arylboronic acids is reported. Using this technology, two different arenes are regioselectively introduced in a vicinal fashion across the terminal alkene of a variety of terminal 1,3-dienes at ambient temperature. Through the action of a chiral bicyclo[2.2.2]octadienyl ligand at -20 C, good enantioselectivity has also been achieved.
