Carbonate esters are 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 organic base. We found that the acid-base interaction of the alcohol and base in the CHCl3 solution plays a key role in enabling the photochemical reaction. This reaction allows practical syntheses of diphenyl carbonate derivatives, haloalkyl carbonates, and polycarbonates, which are important chemicals and materials in industry.

The reaction of pentafluorophenol, 2,2,3,3-tetrafluoropropyl alcohol, and 2,2,3,3,4,4,5,5-octafluoropentyl alcohol with carbon tetrachloride in the presence of aluminum chloride were investigated.The main products from the reaction of pentafluorophenol with these reagents are pentafluorophenoxytrichloromethane, di(pentafluorophenol) carbonate, and tri(pentafluorophenoxy)chloromethane.The ratios of the products depend on the reaction conditions.The use of a large excess of carbon tetrachloride leads to the preferential formation of pentafluorophenoxytrichloromethane.The addition of water promotes the formation di(pentafluorophenyl) carbonate.When heated with carbon tetrachloride and aluminum chloride and subsequently treated with water, 2,2,3,3-tetrafluoropropyl and 2,2,3,3,4,4,5,5-octafluoropentyl alcohols are converted into di(2,2,3,3-tetrafluoropropyl) carbonate and di(2,2,3,3,4,4,5,5-octafluoropentyl) carbonate respectively.
