Insertion Reactions of Diazomethanes and Electrophilic Boranes
摘要:
The electrophilic pentafluoroarylboranes B-(C6F5)(3), PhB(C6F5)(2), and ClB(C6F5)(2) react with (trimethylsilyl) diazomethane, diphenyldiazomethane, or (pentafluorophenyl)diazomethane, affording insertion into the one or two B-C bonds in a facile and high-yielding route to the boranes (Me3SiCH(C6F5))B(C6F5)(2), (Me3SiCH-(C6F5))(2)B(C6F5), (Me3SiCH(C6F5))(Me3SiCH(Ph))B-(C6F5), (C6F5)ClB(CPh2(C6F5)), and (C6F5)(2)B(CH(C6F5)(2)).
