wide variety of alkyl halides with mercury(I) and/or (II) nitrate in 1,2-dimethoxyethane, mercury(II) acetate in acetic acid, aqueous mercury(II) perchlorate, and mercury(II) perchlorate in alcohol solvents have been investigated; as a result, simple high yield procedures for the conversion of alkyl halides into the corresponding nitrate esters, acetate esters, alcohols and ethers have been developed.
Monoacetylated alcohols of symmetric 1,n-diols are synthesized quantitatively by refluxing a suspension of the diols adsorbed on silica gel with acetylchloride.

A green and efficient method was developed for upgrading furfural to 1,10-decanediol diacetate and 1-decanol acetate. 92% yield of the acetates was obtained through the tandem benzoin condensation and hydrodeoxygenation reaction. During the benzoin condensation, furfural was catalyzed into furoin in a quantitative yield by the immobilized NHC catalyst under solvent-free conditions. After dissolving

Iodine in isopropenyl acetate (IPA) is a highly efficientcatalyst for the acetylation of a variety of alcohols, phenols and amines undersolventfree conditions. Primary, secondary, tertiary alcohols, amines and mono to polyhydroxy phenols and anilines with electron donating or withdrawing substituents can be easily acetylated in good to excellent yield at 85–90 °C.
