Carboxylations and decarboxylations [PDF]

Journal of Cellular and Comparative Physiology, 1959
A brief survey of decarboxylation reactions and carboxylation reactions that are known or presumed in biological systems will be presented. While a considerable number of amino acid decarboxylations are known, their mechanisms will not be included in the present discussion but will be reserved for a later paper in the symposium.

Decarboxylative alkenylation [PDF]

Nature, 2017
Olefin chemistry, through pericyclic reactions, polymerizations, oxidations, or reductions, has an essential role in the manipulation of organic matter. Despite its importance, olefin synthesis still relies largely on chemistry introduced more than three decades ago, with metathesis being the most recent addition.

Decarboxylative borylation [PDF]

Science, 2017
Swapping boron acids for carbon acids Carbon-bound boronic acids and their esters are widely used as coupling partners to make carbon-carbon bonds. More recently, these chemicals have garnered pharmaceutical interest in their own right. Li et al.

Decarboxylative Alkynylation [PDF]

Angewandte Chemie International Edition, 2017
AbstractThe development of a new decarboxylative cross‐coupling method that affords terminal and substituted alkynes from various carboxylic acids is described using both nickel‐ and iron‐based catalysts. The use of N‐hydroxytetrachlorophthalimide (TCNHPI) esters is crucial to the success of the transformation, and the reaction is amenable to in situ ...

Decarboxylative sulfation by persulfates

Chemical Science
Decarboxylative radical sulfation is achieved with persulfates functioning as both oxidants and sulfating agents to facilitate C–OSO 3 − bond formation. Synthesis of organosulfates from carboxylic-acid-based drugs may improve their metabolic profiles.
