1] in the spectrum of p-PSDA were assigned as symmetric and asymmetric S=O stretching bands of sulfonyl groups [22].
Recently, we described the Pd-catalyzed intramolecular N-arylation of some 2-aminopyrroles containing a (2-chlorophenyl) sulfonyl group at the 3-position to give a novel tricyclic ring system.
The method is comprised of attaching a reactive group X--Y to a surface of a pigment; and subsequently displacing Y with an organic substrate N--S--ZM to form a surface-modified pigment having attached X--N--S--ZM; wherein X is a sulfonyl, phosphoryl, or 1,3,5-triazine group; Y is fluorine, chlorine, bromine or iodine; N is an amine, an imine, a pyridine, or a thiol group; S is substituted or unsubstituted alkyls, aryls, or polymer chains having a molecular weight range from approximately 300-8000; Z is a carboxyl, sulfonyl, phenolic, phosphoryl, ammonium, trimethylammonium, or tri-butylammonium group; and M is a halide, a negatively charged ion, a proton n salt form, or a cation in salt form.
The buffer contained a cocktail of antiproteases (PMSF [phenylmethyl sulfonyl fluoride], EDTA [ethylenediamine-tetraacetic acid], aprotinin).
3) Hetero atom function (X) = binder functional groups such as phosphato, pyrophosphato, sulfonyl, carboxyl, etc.
Buffered C, tapioca C, cassava C, and vitamin C combined with ribose and methyl sulfonyl methane provide better oral absorption and less intolerance than regular corn-based vitamin C.
These researchers also investigated the photocatalytic activity of synthesized nanocoatings for destruction of pollutants (such as sulfonyl red pigment) and analyzed the effect of factors like heat treatment temperature, thin layer nature, number of layers and structural properties (grain size) on the kinetic of photo destruction reaction.
Novakup surface-modified silica reinforcements can be treated with silanes, titanates, sulfonyl azides, or glass resins.
