Carbon–carbon bonds, ubiquitous in lignin, limit monomer yields from current depolymerization strategies, which mainly target C–O bonds. Selective cleavage of the inherently inert σ-type C–C bonds without pre-functionalization remains challenging. He

Carbon-carbon bond cleavage reactions of organic compounds using transition metal complexes are reviewed. The reactions are first classified by the bond order; (i) carbon-carbon single bond cleavage, (ii) carbon-carbon double bond cleavage, and (iii) carbon-carbon triple bond cleavage. For the ...
with the carbon dioxide containing stable carbon-12. Living organisms use atmospheric carbon dioxide, whether with stable or radioactive carbon, through processes ofphotosynthesisand respiration, and thus their systems contain the constant ratio of carbon-12 to carbon-14 that exists in the atmosphere....

Here we describe an organocatalytic activation of C-C bonds through the addition of an NHC to a ketone moiety that initiates a C-C single bond cleavage as a key step to generate an NHC-bound intermediate for chemo- and stereo-selective reactions. This reaction constitutes an asymmetric ...
