utilized as solvents and reagents for C1 building blocks in organic synthesis. This study reports a novel photo-on-demand in situ synthesis of carbonate esters with CHCl3 solutions containing a mixture of an aromatic or haloalkyl alcohol having relatively high acidity, and an organicbase. We found that the acid–base interaction of the alcohol and base in the CHCl3 solution plays a key role in enabling the
Fluorinated dialkyl carbonates, which serve as environmentally benign phosgene substitutes, were successfully produced from carbon dioxide either directly or indirectly. Nucleophilic addition of 2,2,2-trifluoroethanol to carbon dioxide and subsequent reaction with 2,2,2-trifluoroethyltriflate ( E OTf ) afforded bis (2,2,2-trifluoroethyl) carbonate ( 1 ) in up to 79%. Additionally, carbonate 1 was obtained

The invention relates to a process for producing fluorinated carbamates comprising the reaction between an amine or polyamine and a fluorinated carbonate, in the presence of a catalyst which does not contain metals and comprises at least one tertiary amine group. The process can also comprise an additional step in which the carbamates are transformed into the corresponding isocyanates.
