Photoredox/Cobalt Dual-Catalyzed Decarboxylative Elimination of Carboxylic Acids: Development and Mechanistic Insight
Cartwright, Kaitie C.,Joseph, Ebbin,Comadoll, Chelsea G.,Tunge, Jon A.
, p. 12454 - 12471 (2020/09/09)
Recently, dual-catalytic strategies towards the decarboxylative elimination of carboxylic acids have gained attention. Our lab previously reported a photoredox/cobaloxime dual catalytic method that allows the synthesis of enamides and enecarbamates directly from N-acyl amino acids and avoids the use of any stoichiometric reagents. Further development, detailed herein, has improved upon this transformation's utility and further experimentation has provided new insights into the reaction mechanism. These new developments and insights are anticipated to aid in the expansion of photoredox/cobalt dual-catalytic systems.
Malononitrile as acylanion equivalent
F?rster, Sebastian,Tverskoy, Olena,Helmchen, Günter
experimental part, p. 2803 - 2806 (2009/05/26)
The oxidation of derivatives of malononitrile with peracid in methanol proceeds with loss of the cyano groups to yield methyl esters in high yield. The method was applied to a variety of malononitrile derivatives, some of which were prepared by Pd- or Ir-catalyzed asymmetric allylic substitution. Georg Thieme Verlag Stuttgart.
The use of - for the carbonylation of primary, secondary and allylic halides
Davies, Stephen G.,Smallridge, Andrew J.,Ibbotson, Arthur
, p. 195 - 201 (2007/10/02)
The tricarbonyl nitrosyl ferrate anion (1) is an efficient carbonylation reagent for the formation of methyl esters from primary and secondary alkyl and benzyl halides.The carbonylation of allyl halides results in the exclusive formation of β,γ-unsaturated esters.Studies of the catalytic use of 1 are also described.
