Ruthenium‐Mediated Distal C−H Activation
Chemistry – An Asian Journal, 2018AbstractAddressing remote C−H functionalization is a prominent challenge in the field of homogeneous catalysis. The past two decades have accounted for major developments in this domain, proclaiming efficient selectivity at the meta and para positions. Recognizing such transformations remains significant, owing to their importance in the biological and

Iron-Catalyzed C–H Bond Activation
Chemical Reviews, 2017Catalytic C-H bond activation, which was an elusive subject of chemical research until the 1990s, has now become a standard synthetic method for the formation of new C-C and C-heteroatom bonds. The synthetic potential of C-H activation was first described for ruthenium catalysis and is now widely exploited by the use of various precious metals.

Enantiospecific CH Activation Using Ruthenium Nanocatalysts
Angewandte Chemie, 2015AbstractThe activation of CH bonds has revolutionized modern synthetic chemistry. However, no general strategy for enantiospecific CH activation has been developed to date. We herein report an enantiospecific CH activation reaction followed by deuterium incorporation at stereogenic centers.

Transition metal-catalyzed carbonylation reactions represent an enormous toolbox for CO–X bond formation (X = C, N, O, etc.). While most coupling reactions take place with heteronucleophiles nowadays, carbonylations including C–H activation are attracting more and more attention because the use of stoichiometric amounts of organometallic reagents can ...

Transition‐metal‐catalyzed C–H activation and C–C formation have been receiving considerable attention because of their high atom economy and synthesis efficiency. Iron is widely used in catalytic reactions because it has the advantages of abundance, low cost, accessibility, and environmental friendliness.

Polymer Chemistry Methods to oxidize carbonhydrogen (C–H) bonds under mild conditions are showing increasing promise in streamlining small-molecule synthesis. Chen et al. report an application tailored instead to a macromolecule: polyethylene. The world's most common plastic has proven hard to tweak without damaging its structural integrity, but a ...
