title: Rhodium(I)-catalyzed one-pot synthesis of dialkyl ketones from methanol and alkenes through directed sp3 C-H bond activation of N-methylamine.
abstract: The hydroacylation of methanol with alkenes was developed using a catalytic system consisting of Rh(I), 2-amino-4-picoline and benzoic acid; the reaction is speculated to occur by the initial N-methylation of 2-amino-4-picoline with methanol, and the subsequent dehydrogenation of the resulting N-methylamine, followed by double chelation-assisted hydroimination of alkene with the imine to give dialkyl ketones after hydrolysis.
