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.

Viggert, R. V.,Maksimenko, N. N.,Rubleva, L. I.,Derevyanko, S. V.
, p. 1295 - 1298 (2007/10/02)
The sulfonylation of phenols by aromatic sulfonyl chlorides in the presence of pyridine bases in nitrobenzene was studied by potentiometric titration.A linear dependence was found between the logarithms of the catalytic constants and the ?-Hammett constan
