Electron Donor-Acceptor Complex Enabled Decarboxylative Sulfonylation of Cinnamic Acids under Visible-Light Irradiation

Visible-light-induced decarboxylative sulfonylation of cinnamic acids with aryl sulfonate phenol esters enabled by the electron donor-acceptor complex is developed. The method offers a mild and green approach for the synthesis of vinyl sulfones with excellent functional group compatibility under photocatalyst and oxidant-free conditions.

Kinetics and Mechanism of Michael Addition of Pyrrolidine and Piperidine to a Polarized Double Bond

The kinetics and mechanism of reaction of pyrrolidine and piperidine addition to trans-1-phenyl-2-(benzenesulphonyl)ethene (I) have been examined.The mechanism of addition of amines to compound I has been found to be analogous to that proposed for the reaction of trans-chalcone with amines.The addition of amine to the double bond of compound I takes place in a direct way.In the reaction of addition of amines to the polarized double bond three pathways can be distinguished: dimolecular one with participation of amide ions, dimolecular one with participation of free amine, and trimolecular one.
