Enantiospecific CH Activation Using Ruthenium Nanocatalysts.

The activation of CH bonds has revolutionized modern synthetic chemistry. However, no general strategy for enantiospecific CH activation has been developed to date. We herein report an enantiospecific CH activation reaction followed by deuterium incorporation at stereogenic centers. Mechanistic studies suggest that the selectivity for the α-position of the directing heteroatom results from a four-membered dimetallacycle as the key intermediate. This work paves the way to novel molecular chemistry on nanoparticles. [ABSTRACT FROM AUTHOR]
