摘要

描述了一种利用氟化溴化物和锡（II）盐对末端炔进行1,2-氟烷基化/锡基化的方法。该反应是在光催化条件下进行的，涉及自由基在三键处加成，然后乙烯基自由基与锡（II）相互作用。将反应混合物与丁基溴化锌处理得到乙烯基三丁基锡烷，其可参与Stille交叉偶联或进行碘烷基化。

Radical 1,2-fluoroalkylation/stannylation of terminal alkynes

A method for the radical 1,2-fluoroalkylation/stannylation of terminal alkynes using fluorinated bromides and a tin(II) salt is described. The reaction is performed under photocatalytic conditions and involves radical addition at the triple bond followed by interaction of the vinyl radical with tin(II). Treatment of the reaction mixture with butylzinc bromide leads to vinyl tributylstannanes, which can be involved in the Stille cross-coupling or subjected to iododestannylation.

期刊介绍： The Journal of Fluorine Chemistry contains reviews, original papers and short communications. The journal covers all aspects of pure and applied research on the chemistry as well as on the applications of fluorine, and of compounds or materials where fluorine exercises significant effects. This can include all chemistry research areas (inorganic, organic, organometallic, macromolecular and physical chemistry) but also includes papers on biological/biochemical related aspects of Fluorine chemistry as well as medicinal, agrochemical and pharmacological research. The Journal of Fluorine Chemistry also publishes environmental and industrial papers dealing with aspects of Fluorine chemistry on energy and material sciences. Preparative and physico-chemical investigations as well as theoretical, structural and mechanistic aspects are covered. The Journal, however, does not accept work of purely routine nature. For reviews and special issues on particular topics of fluorine chemistry or from selected symposia, please contact the Regional Editors for further details.
