Most of the reactions proceeded in anti. Both hydrogen atoms come from h2o. In the borrowing hydrogen catalysis,.
Cooperative bimetallic radical catalysis that enables asymmetric hat without the formation of carbon radicals. By selecting an appropriate phosphine, a more reactive olefin can be selectively hydrogenated. Herein, we report a new conceptual approach:
Radical hydrogenation via hydrogen atom transfer (hat) to alkenes is an increasingly important transformation for the formation of thermodynamic alkane isomers. Hydrogenation at β position is the rate determining. Hydrometalation of alkenes with transition─metal hydrides(m─h) represents an important step in transition─metal─ catalyzed transformations.
