Organic Synthesis
Sulfonamides can be prepared in the laboratory in many ways. For example, by the reaction of sulfonyl chlorides with amines in the synthesis of sulfonylmethylamide. A readily available sulfonyl chloride source is tosyl chloride.
Triflimide or triflimidic acid HN(Tf)2 (bis(trifluoromethane)sulfonimide) is the formal adduct of triflic acid and ammonia. Phenyl triflimide is a triflating reagent. The related metal triflimidates are used as catalysts. The anion bistriflimide is hydrophobic.

Famous quotes containing the words organic and/or synthesis:
“When life has been well spent, age is a loss of what it can well spare,—muscular strength, organic instincts, gross bulk, and works that belong to these. But the central wisdom, which was old in infancy, is young in fourscore years, and dropping off obstructions, leaves in happy subjects the mind purified and wise.”
—Ralph Waldo Emerson (1803–1882)
“The spider-mind acquires a faculty of memory, and, with it, a singular skill of analysis and synthesis, taking apart and putting together in different relations the meshes of its trap. Man had in the beginning no power of analysis or synthesis approaching that of the spider, or even of the honey-bee; but he had acute sensibility to the higher forces.”
—Henry Brooks Adams (1838–1918)
