Cobalt-Catalyzed Esterification of Amides
Bourne-Branchu, Yann,Gosmini, Corinne,Danoun, Grégory
supporting information, p. 10043 - 10047 (2017/08/01)
The first cobalt-catalyzed amide activation of N-Boc-amides, and their conversion into esters, is reported here. This new methodology presents a very practical process that does not require an inert atmosphere, uses an inexpensive cobalt catalyst, and proceeds under mild reaction conditions. This catalytic system has a broad substrate scope and has been shown to be highly efficient, with catalyst loadings as low as 1 mol %.
The Invention of Radical Reactions. XXXIII Homologation Reactions of Carboxylic Acids by Radical Chain Chemistry
Barton, Derek H. R.,Chern, Ching-Yuh,Jaszberenyi, Joseph Cs.
, p. 407 - 426 (2007/10/02)
Various carbon radicals can be generated from carboxylic acids via the corresponding Barton esters.These radicals can be used for the synthesis of longer chain homologues of the original acids.
Chain-elongation and Degradation of Carboxylic Acids by Barton-ester Based Radical Chemistry

The reaction of α-trifluoroacetoxy acrylates and acrylonitriles with carbon radicals formed from carboxylic acids gives adducts that can be transformed into vic-diols, esters, amides, and homoaldehydes in good to high yield.Aldoses can be smoothly degraded to the corresponding nor- or bis-nor compounds using radical chemistry.
