Potassium carbonate: a highly efficient catalyst for the acylation of alcohols, phenols and thiols under mild conditions
A general, mild and efficient protocol has been developed for the synthesis of esters and thioesters. The process has been taking place using tetra n-butylammonium iodide (TBAI) as a phase-transfer catalyst and in the presence of potassium carbonate (K2CO3). A wide range of esters and thioesters was prepared in high yields and suitable times by the treatment of alcohols, phenols and thiols with...

متن کاملThe 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...
