Investigating the formation of dialkyl carbonates using high speed ball milling

We investigated the synthesis of dialkyl carbonates under solvent-free high speed ball milling conditions. We converted various metal carbonates with the assistance of metal complexing reagents into a variety of dialkyl carbonates. We also observed the increased reactivity of urea under similar reaction conditions. The Royal Society of Chemistry.

Method for synthesis of organic carbonates

In the present invention, provided is a method for synthesizing organic carbonates, comprising the steps of providing a mixture solution of ionic liquid and alcohol activating reagent; introducing carbon dioxide sources with acidity and alkalinity to the mixture solution; and making the alcohol react with the carbon dioxide source and accordingly obtaining products through the binding of the alcohol and the carbon dioxide source.COPYRIGHT KIPO 2015

Metal-free synthesis of cyclic and acyclic carbonates from CO2 and alcohols

Diverse cyclic and acyclic carbonates such as ethylene carbonate, propylene carbonate, glycerol carbonate, and dimethyl carbonate were synthesized in moderate to good yields by the direct coupling of the corresponding alcohols with carbon dioxide in the absence of metal catalysts and inorganic bases. The direct carbonation mechanism of alcohols in the presence of 1,8-diazabicyclo[5. 4.0]undec-7-ene, 1-butyl-3-methylimidazolium hexafluorophosphate, and dibromomethane was probed by 18O-labeling experiments and chiral alcohol experiments.

Making kinetic and thermodynamic enolates via solvent-free high speed ball milling

We investigated the ability to selectively form products arising from a kinetic or a thermodynamic enolate under solvent-free high speed ball milling conditions. Using 2-methylcyclohexanone as the substrate and sodium hydroxide or lithium hexamethyldisila
