This presentation will describe the first multi-gram one-step synthesis of 3,4-difluorofuran from 3,3,4,4-tetrafluorotetrahydrofuran. To date, NMR chemical shift data and physical properties have been theoretical (ab initio calculations and models) and not experimental. 3,4-Difluorofuran was synthesized using a double elimination mechanism with a sterically hindered alkoxide in a manner similar to published procedures for 3,4-difluoropyrrole. 1H-19F NMR shifts and coupling constants will be compared with experimentally derived chemical shifts from DFT calculations. The polymerization of 3,4-difluorofuran using oxidative chemical and electrochemical techniques will be described, And the conductive and physical properties of poly-3,4-difluorofuran in conjunction with initial characterization (TGA, XPS) of Co2+ metallopolyfurans will be reported.
