Dehydrogenation of Inert Alkyl Groups via Remote C−H Activation: Converting a Propyl Group into a π-Allylic Complex
摘要:
Pd(OAC)(2)-inediated dehydrogenation of an alkyl group to a double bond or a eta(3)-allylic complex via sp(3) C-H bond activation and allylic oxidation is reported. A novel redox is Proposed for this double oxidation under oxidant-free conditions. A catalytic protocol using benzoquinone as the stoichiometric oxidant has also been developed for the dehydrogenation of cyclopentylcarboxamides.
