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.

An iodine-induced synthesis of sulfonate esters via cross-coupling reactions of sodium sulfinates with phenols is reported. This synthetic route is low-cost, facile, green and efficient, and could afford the target products with good to excellent yields u

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

The sulfonylation of p-chlorophenol by p-bromobenzenesulfonyl chloride in the presence of pyridine bases in nitrobenzene was investigated by potentiometric titration.A linear relation was obtained butween the logarithms of the catalytic constants and the basicity of the catalysts (β = 1.04) and the sensitivity of the reaction to the effect of substituents in the pyridine (ρ = -6.5).The effect of the leaving group (the kBrc/kClc ratio) is large and equal to 33.5.On the basis of the obtained data and of previous investigations it is suggested that catalysis by pyridine bases in the sulfonylation of phenols has a nucleophilic mechanism.
