ZSM-5-SO3H: An Efficient Catalyst for Acylation of Sulfonamides Amines, Alcohols, and Phenols under Solvent-Free Conditions
Sulfonamides amines, alcohols, and phenols were efficiently acylated with carboxylic acid anhydrides and chlorides using ZSM-5-SO3H as catalyst under mild and solvent-free conditions. Also, direct esterification of alcohols with carboxylic acids occurred readily in the presence of this catalyst. Different types of amides and esters were obtained in moderate to high yields and purity after a sim...

15 صفحه اولThe zinc chromium ferrite magnetic nanoparticles ZnCrFeO4: An efficient catalyst for acetylation of alcohols, phenols and amines under solvent-free conditions
In this study, the zinc chromium ferrite magnetic nanoparticles ZnCrFeO4 are synthesized via sol-gel method and characterized by X-ray diffraction (XRD) analysis, Fourier transform infrared spectroscopy (FT-IR) and scanning electron microscopy (SEM). The XRD analysis showed that ZnCrFeO4 has single-phase cubic structure. The synthesized ZnCrFeO4 has been used as an efficient catalyst for acetyl...
متن کاملMelamine trisulfonic acid: A new, efficient and reusable catalyst for the protection of alcohols, phenols, aldehydes and amines
Tetrahydropyranylation of alcohols and phenols, acetylation of aldehydes and N-Boc protection of amines are efficiently catalyzed by melamine trisulfonic acid (MTSA). All reactions were performed at room temperature in good to high yields.
