Activation of Cyanate Anions by Phosphine Radical Cations Enables Formal Hydrocarbamoylation of Alkenes. [PDF]

Angew Chem Int Ed Engl
A photocatalytic formal hydrocarbamoylation reaction that employs a cyanate anion as the C1 source and provides N‐acyl iminophosphorane products from activated alkenes is described. Mechanistic investigations suggest generation of a phosphoranyl radical by addition of the cyanate anion to a phosphine radical cation, which enables the delivery of the ...
