A general synthesis method for aromatic and aliphatic, cyclic, linear, symmetric and asymmetric difluoromethylenedioxy derivatives is described. The method provides pathways to construct OC[F.sub.2]Cl group and OC[F.sub.2]O moiety.

A synthesis of a wide range of different aliphatic, aromatic, and heterocyclic N-(trifluoromethyl)amides along with aromatic N-(difluoromethylene)-N-(trifluoromethyl)amine derivatives has been developed. The starting materials are the easily available isothiocyanates, and the fluorinating reagent is the commercially available bromine trifluoride. The reaction is performed under mild conditions, and the fluorinated amides and amines are produced in moderate to high yields. [ABSTRACT FROM AUTHOR]

A general preparation for aromatic and aliphatic, cyclic as well as linear, symmetric and asymmetric difluoromethylenedioxy derivatives is described. The alcohols were reacted with thiophosgene to give thiocarbonates, which in turn were reacted with BrF3. The fluorination step is complete in seconds with moderate to high yields under mild conditions. [ABSTRACT FROM AUTHOR]
