It was demonstrated that ionicliquids are superb recyclable media for copper catalyzed reactions using catalytic olefination reaction as an example. As a result a novel green access to the halogenoalkenes was elaborated. Possibility to perform up to five reaction cycles without catalyst leaching and decreasing of the yield was demonstrated. A number of various ionicliquids was screened and 1-buty
This work describes the first transition metal-free stereospecificsynthesis of (E)-(1-fluoro-2-arylvinyl)phosphine boranes through the addition of diarylphosphido-boranes to gem-bromofluoroalkenes at room temperature. The reaction proceeds well under very mild conditions...
A halon-free method for the synthesis of ‑bromofluoroolefins utilizing ethyldibromofluoro-acetate is disclosed via a Wittigtypereaction. The reaction system takes advantage of inexpensive and readily available reagents. The method was applied to a wide variety of aryl aldehydes. Both electron donating and electron withdrawing moieties on the aryl ring were tolerated and the desired olefin products
