Platinum(II) Olefin Hydroarylation Catalysts: Tuning Selectivity for the anti-Markovnikov Product

摘要

Pt-II complexes containing unsymmetrical (pyridyl)pyrrolide ligands are shown to catalyze the hydroarylation of unactivated alkenes with selectivity for the anti-Markovnikov product. Substitution on the pyrrolide portion of the ligand allows effective tuning of the selectivity to anti-Markovnikov alkylarene products, whereas substitution on the pyridyl portion can promote competitive alkenylarene production.
