ON THE SPECIFIC USE OF PLATINUM CATHODES TO CONVERT PRIMARY ALKYL HALIDES TO ALKENES

摘要

In a superdry DMF-TMABF_4 medium, reduction of primary alkyl bromides and chlorides at a platinized platinum cathode affords the corresponding alkene in nearly quantitative yield. An ionometallic layer, (Pt_n~- TMA~+, TMABF_4), formed on the surface of the cathode promotes the reduction of residual water to OH~-, which reacts with an alkyl halide to give an alkene (E2 elimination).
