Chemistry is the experimental and theoretical study of materials on their properties at both the macroscopic and microscopic levels. 142-73-4, Name is Iminodiacetic acid, molecular formula is C4H7NO4. In an article, author is Heravi, Majid M.,once mentioned of 142-73-4, SDS of cas: 142-73-4.
Heteropolyacids as green and reusable catalysts for the synthesis of isoxazole derivatives
Heteropolyanions with different structures, including Keggin, Dawson, Preyssler, mixed addenda, and sandwich types, catalyzed the formation of 1,3-diphenyl-isoxazole from the condensation of 1,3-diphenyl-propane-1,3-dione and hydroxylamine hydrochloride in different solvents and under heating conditions. Our data vividly indicate that H3PW11CuO40 is the catalyst of choice and could catalyze the synthesis of other isoxazole derivatives in high yields and good selectivities.
