fluorides with secondary boranes pinacolborane (HBpin), catecholborane (HBcat), 9‐borabicyclo(3.3.1)nonane (9‐BBN) and Piers’ borane (HB(C6F5)2) are described. While HBcat, 9‐BBN and HB(C6F5)2 reduce Ad‐F to Ad‐H, the latter borane was shown to react with secondary and primary fluoroalkanes, affording C−F borylation, while benzyl fluorides undergo Friedel–Crafts chemistry.
烷基氟化物1-氟金刚烷(Ad-F),氟代环己烷(Cy-F),1-氟戊烷(Pent-F)和苄基氟化物与仲硼烷频哪醇硼烷(HBpin),儿茶酚硼烷(HBcat),9-硼杂环( 3.3.1)描述了壬烷(9-BBN)和Piers'硼烷(HB(C 6 F 5)2)。HBcat,9-BBN和HB(C 6 F 5)2将Ad-F还原为Ad-H时,后者的硼烷与仲和伯氟代烷烃反应,提供CF硼化作用,而苄基氟化物则经历了Friedel-Crafts化学。
