5‐Hydroxymethylfurfural (HMF) is a key platform chemical that may be obtained from various cellulosic (biomass) derivatives. Previously, it has been shown that ionic liquids (ILs) facilitate the catalytic conversion of glucose into HMF. Herein, we demonstrate that the careful design of the IL cation leads to new ionic solvents that enhance the transformation of glucose and more complex carbohydrates

Alternative approaches to the preparation of azolylethyl benzhydryl ethers have been studied. It was shown that the reaction of diphenylmethyl halide with 2-(azol-1-yl)ethanol in the presence of triethylamine is the optimum way. An efficient method for the synthesis of 2-(imidazol-1-yl)ethanol using phase-transfer catalysis has been developed.
