Exempel på hur man kan använda SULFONYL i en mening

• Cyanogen chloride is a precursor to the sulfonyl cyanides and chlorosulfonyl isocyanate, a useful reagent in organic synthesis.
• also catalyses the free radical addition of sulfonyl chlorides to alkenes; the alpha-chlorosulfone may then undergo elimination with a base to give a vinyl sulfone product.
• In organosulfur chemistry, a sulfonyl group is either a functional group found primarily in sulfones, or a substituent obtained from a sulfonic acid by the removal of the hydroxyl group, similarly to acyl groups.
• Crosslinking reactions are also found, where condensation of two sulfonic acid groups yields a sulfonyl crosslink.
• In water, the sulfonyl chloride group of unreacted Texas Red molecules hydrolyses to sulfonate and the molecule becomes the very water-soluble sulforhodamine 101 which is easy to wash out selectively.
• This protocol takes advantage of a stable sulfonyl azide, rather than tosyl azide, for the in situ generation of the Ohira−Bestmann reagent.
• Sulfolane is classified as a sulfone, a group of organosulfur compounds containing a sulfonyl functional group.
• The stability of sulfonyl halides decreases in the order fluorides > chlorides > bromides > iodides, all four types being well known.
• The simplest organic sulfonyl chloride, it is used to make methanesulfonates and to generate the elusive molecule sulfene (methylenedioxosulfur(VI)).
• Various serine protease inhibitors (aprotinin, phenylmethyl sulfonyl fluoride, leupeptin, and 4-(2-aminoethyl)-benzenesulfonyl fluoride).
• Synthesis of the HCl salt has led to a significant explosion, with expected explosive byproducts of sulfonyl diazide or hydrazoic acid being present.
• Open ocean and coastal waters and large lakes serve as core media for sampling perfluorooctane sulfonic acid (PFOS), its salts and perfluorooctane sulfonyl fluoride (PFOS-F).
• Unlike the sulfur atom in sulfonyl halides and sulfenyl halides, the sulfur atom in sulfinyl halides is chiral, as shown for methanesulfinyl chloride.
• Methylation reactions in which a sulfonyl anion acts as a nucleophile and a methyl (arenesulfonate) serves as an electrophile were known to occur, but it was proposed that they could proceed either intermolecularly or intramolecularly.
• The protecting group 2-trimethylsilylethanesulfonyl chloride (SES-Cl) for primary and secondary amino groups is accessible by the reaction of vinyltrimethylsilane with sodium hydrogensulfite and TBPB to the sodium salt of trimethylsilylethanesulfonic acid and the subsequent reaction with thionyl chloride to the corresponding sulfonyl chloride.
• Known sulfonyl nitrenes include methyl sulfonyl nitrene, trifluoromethyl sulfonyl nitrene, and tolyl sulfonyl nitrene.
• Organic compounds such as alkyl halides, hydroxyls (hydroxyl nitriles and carbohydrates), carbonyl (aldehydes/ketones/esters/alcohols), and sulfur (sulfonyl derivatives) can all undergo ammonolysis in liquid ammonia.
• In 2012, his group published rhodium catalyzed intermolecular amidation of arenes using sulfonyl azide as a nitrene precursor.
• Glycosylated N-sulfonylamidines: Highly efficient copper catalyzed multicomponent reaction with sugar alkynes, sulfonyl azides and amines: Santanu Mandal, Harsh Mohan Gauniyal, Kausikisankar Pramanik, Balaram Mukhopadhyay, Journal of Organic Chemistry 2007, 72, 9753–9756.
• Sulfinyl nitrenes are unstable and react with themselves to yield sulfonyl nitrenes, disulfides or polymerise to trioxotrithiztriazes.
