A series of diphosphine ligands bearing ester- and ether-modified diphenylether backbones have been prepared. The introduction of carboxylic acid or ether auxiliaries in the ortho-positions relative to the diphenylphosphine groups was achieved via straigh

Four new difluorinated tetra- and pentabromo BDE internal standards for GC-MS/GC-ECD analysis, 2F-BDE 47, 2F-BDE 85, 2F-BDE 99 and 2F-BDE 119, have been prepared in 98-99.0% purity, mainly by coupling of the new tribromodifluorophenols (19-21) and symmetr
Preparation process of fluorine substituted aromatic compound

A preparation process of a fluorine substituted aromatic compound comprising reacting an alkali metal or alkali earth metal salt of an aromatic compound having a hydroxy group with an organic fluorinating agent is disclosed. As a representative fluorinating agent, a bis-dialkylamino-difluoromethane compound, for example, 2,2′-difluoro-1,3-dimethylimidazolidine, is exemplified. According to the process, an industrially useful fluorinated aromatic compound, for example, a fluorobenzene, a fluorine substituted benzophenone, a fluorine substituted diarylsulfone can be prepared with ease in economy without specific equipment.
