One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, such as the rate of change in the concentration of reactants or products with time. 58446-52-9, Name is 1-Phenylicosane-1,3-dione, formurla is C26H42O2. In a document, author is CLERICI, F, introducing its new discovery. COA of Formula: C26H42O2.
N-SULFONYLAMIDINES .4. INTRAMOLECULAR CYCLIZATION OF N-SULFONYLAMIDINES OF 2-OXOACIDS – A NEW SYNTHESIS OF 3-AMINOISOTHIAZOLE S,S-DIOXIDES
N-alkylsulfonylamidines of alpha-ketoacids 3 bearing both a carbonyl group and at least one H-atom near to the SO2 group give easily an intramolecular ring-closure reaction by action of potassium t-butoxide producing the 3-amino-4,5-dihydro-4-hydroxy-isothiazole S,S-dioxides 4. Compounds 4 are transformed by thionyl chloride into the corresponding chloro-derivatives 5 which in turn are dehydrochlorinated by potassium carbonate to substituted 3-amino-isothiazole S,S-dioxides 6.
