摘要:The present invention pertains generally to the field of chemical synthesis, and more particularly to methods for the chemical synthesis of a thiosulfonic acid of Formula (1) by a step of periodate mediated oxidative coupling of a thiosulfonic acid of Formula (2) with an aniline of Formula (3), as described herein. The present invention also relates to such methods which incorporate one or more additional (subsequent and/or preceding) steps, for example, to prepare compounds of Formula (5) from compounds of Formula (1); to prepare compounds of Formula (6) from compounds of Formula (5); and to prepare compounds of Formula (2) from compounds of Formula (4), as described herein.

标 题 :Synthesis of bleach activators
发明人：BURNS MICHAEL E; SIMPSON ANTHONY J
权利人:PROCTER & GAMBLE
摘要:The synthesis of phenol sulfonate esters of alkanoyl amino acids is conducted in the presence of aqueous base to provide bleach activator compounds. Thus, the acid chloride of N-nonanoyl-6-aminocaproic acid is reacted with the sodium salt of p-phenol sulfonate in the presence of water at a pH in the range of about 9 to about 12 to yield the corresponding phenol sulfonate ester. The synthesis of the phenol sulfonate ester of the monononyl amide of adipic acid is also illustrated.

权利人:PENN STATE RES FOUND
摘要:The invention relates to sulfonimide bearing phenolic compounds and the use of those compounds to produce polyphosphazenes functionalized by one or more of those compounds alone, or in combination with cosubstituents. The invention also relates to blends of sulfonimide functionalized phosphazene polymers with other polymers, membranes formed of the functionalized polymers, and the use of those membranes in devices such as fuel cells.

标题 :Manufacture of 3-halosulfonylthiophene-carboxylic acid compounds
发明人：ROSSY PHILLIP A; HOFFMANN WERNER; MUELLER NORBERT
权利人:BASF AG
摘要:3-Halosulfonylthiophene-carboxylic acid compounds are manufactured by reacting 3-ketothiophane-carboxylic acid compounds with sulfonic acid compounds, reacting the end product from the 1st reaction stage with alkali metal polysulfides, reacting the end product from the 2nd stage with a dehydrogenating agent and finally reacting the end product from the 3rd stage with halogen and water. The products are starting compounds for the manufacture of drugs, dyes and crop protection agents and have an anti-inflammatory, analgesic and anti-rheumatic action. In particular, the end products I are starting materials for the manufacture of sweeteners which are non-toxic and free from an after-taste, flavor-improving agents, diabetic aids and feedstuffs, and provide the means of a simple and economical synthesis of thiophene-saccharins.
