Abstract

The sp(3)C-H bond functionalisation of 2-pyridyl ethanols upon reaction with alkenes, in the presence of a [RuCl2(arene)]2 catalyst and Cu(OAc)2·H2O, is performed under mild conditions without additional base. This reaction proceeds via a tandem alcohol dehydrogenation/alkylation with alkenes of the resulting ketone at its α sp(3)C-H bond.
