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. 591-11-7, Name is 5-Methylfuran-2(5H)-one, formurla is C5H6O2. In a document, author is Kayukov, Ya. S., introducing its new discovery. Recommanded Product: 591-11-7.
Potassium 1,1,3,3-Tetracyano-2-[2-(methoxycarbonyl)benzoyl]prop-2-enide in the Synthesis of Spiro-Fused Isobenzofuran Derivatives
Successive treatment of potassium 1,1,3,3-tetracyano-2-(2-(methoxycarbonyl)benzoyl)prop-2-enide with concentrated sulfuric acid and water gave 2-(5 ‘-amino-4 ‘-cyano-3-oxo-3H,3 ‘ H-spiro[[2]benzofuran-1,2 ‘-furan]-3 ‘-ylidene)propanedinitrile. The reaction of the title compound with sodium hydroxide, followed by neutralization with sulfuric acid afforded 4 ‘-amino-3,3 ‘,6 ‘-trioxo-2 ‘,3 ‘,5 ‘,6 ‘-tetrahydro-3H-spiro[[2]benzofuran-1,1 ‘-pyrrolo[3,4-c]pyridine]-7 ‘-carbonitrile.
