摘要

A catalytic amount of ruthenium (III) acetylacetonate (2 mol%)[Ru (acac) 3] enables solvent- free tetrahydropyranylation of different types of alcohols and phenols at ambient temperature in moderate to excellent yields. Notably, selective monoprotection of diols can be achieved chemoselectively. Furthermore, the catalyst could be recovered and reused if necessary. Key words: tetrahydropyranyl ethers, protecting groups, ruthenium (III) acetylacetonate, ...
