Abstract
Solvent polarity and nature of the ligands on the catalyst are crucial factors that control the regioselectivity of the Rh(II) promoted intramolecular 1,6 C–H insertions versus the β-elimination. We have explored the best conditions for the preparation of flavanones and chromenes through this approach. The procedure is also an excellent way of preparing stereochemically pure Z aryl-alkenes.
