Convenient preparation of fatty ester cyclic carbonates
The cyclic carbonate moiety finds many industrial applications because of its unique chemistry and properties. Phosgene, a highly toxic and corrosive reagent, has been utilized in the past to prepare low yields of fatty ester compounds (1) that contain a five-membered cyclic carbonate group. Herein, we show (CH3)4N HCO3, tetramethylammonium hydrogen carbonate (TMAHC), to react efficiently with ...
متن کاملA Convenient Preparation of Anhydrous Alkali Metal Thiocarboxylates
Alkali metal salts of thiocarboxylic acid, especially anhydrous salts, are of the most important starting materials. However, only a limited amount of information on their preparation and spectral data has been available because of their strong hygroscopicity [1]. Recently, the convenient preparation methods of a series of anhydrous alkali metal dithiocarboxylates were developed [2]. This resul...
متن کاملThe convenient preparation of stable aryl-coated zerovalent iron nanoparticles
A novel approach for the in situ synthesis of zerovalent aryl-coated iron nanoparticles (NPs) based on diazonium salt chemistry is proposed. Surface-modified zerovalent iron NPs (ZVI NPs) were prepared by simple chemical reduction of iron(III) chloride aqueous solution followed by in situ modification using water soluble arenediazonium tosylate. The resulting NPs, with average iron core diamete...
