paper describes the hydrofluorination of alkenes through sequential H− and F+ addition under palladium catalysis. The reaction is cis specific, thus providing access to benzylic fluorides. The mechanism of this reaction involves an ionic pathway and is distinct from known hydrofluorinations involving radical intermediates. The first catalytic enantioselective hydrofluorination is also disclosed.
本文描述了通过连续的^ h烯烃的氢氟化-和F +除了在钯催化下。该反应是顺式 特异性的,因此提供了获得苄基氟化物的途径。该反应的机理涉及离子途径,并且与涉及自由基中间体的已知氢氟化反应不同。还公开了第一催化对映选择性氢氟化。
