Spontaneous Oxidation of Aromatic Sulfones to Sulfonic Acids in Microdroplets
Journal of the American Society for Mass Spectrometry, 2022Reactions in microdroplets can be accelerated and can present unique chemistry compared to reactions in bulk solution. Here, we report the accelerated oxidation of aromatic sulfones to sulfonic acids in microdroplets under ambient conditions without the addition of acid, base, or catalyst.

AbstractThe sulfonation of benzene and toluene with sulfur trioxide without solvent has been studied extensively.With benzene at low conversion benzenesulfonic acid and diphenylsulfone are the only products. At 25° the sulfone: sulfonic acid ratio changes from 0.2 to 0.6 on varying the SO3 : C6H6 ratio from 0.13 to 1.3.

The metabolism of the surfactants dodecyl sulfonate and hexadecyl sulfonate in the rat
Toxicology and Applied Pharmacology, 1978Abstract When [1-14C]dodecyl sulfonate and [1-14C]hexadecyl sulfonate were administered orally and ip to free-ranging rats and iv to anesthetized rats, the major route of excretion of radioactivity was urinary. Small amounts only of parent surfactant appeared in the feces of animals dosed orally with [1-14C]dodecyl sulfonate, but large amounts of [1 ...

Dioxygen mediated hydroacylation of vinyl sulfonates and sulfones on water
Chem. Commun., 2010Herein we report a mild, facile method for the preparation of 1,4-keto-sulfonates and sulfones on water. Further synthetic manipulations can result in products that are not readily accessed by hydroacylation of electron rich alkenes.

The polysulfonylamines bis(methylsulfonamido) sulfone and bis(trifluoromethylsulfonamido) sulfone
Acta Crystallographica Section C Crystal Structure Communications, 2003Bis(methylsulfonamido) sulfone, C(2)H(8)N(2)O(6)S(3) or SO(2)(NHSO(2)CH(3))(2), was synthesized from imidobis(sulfonyl chloride), HN(SO(2)Cl)(2), and bis(trimethylsilyl)methane, CH(2)[Si(CH(3))(3)](2), in chlorotrimethylsilane solution. In the solid state, there are two independent molecules linked by two N-H...O hydrogen bridges into infinite chains ...
