  Intramolecular Reactivity of Arylcarbenes: Derivatives of o-Tolylcarbene

  摘要：

  Various CH(2)X groups have been attached to the ortho position of phenylcarbene. If 2'- or 3'-C-H bonds are present, as in 23 (X = Me), 71 (X = CMe(3)), and 58 (X = SiMe(3)), C-H insertion leading to five- or six-membered rings predominates in the gas phase and competes with intermolecular reactions in solution. The formation of benzocyclobutenes via insertion into 1'-C-H bonds is a very minor reaction path of 23 and 71. In contrast, 58 produces substantial amounts of the benzocyclobutene 59 by way of C-Si insertion, particularly in the gas phase. Insertion into the Si-Me bonds of 58 also occurs while the C-F bonds of 37 (X = CF3) and 50 (X = Fl are inert. In the gas phase, 37 and 50 give mainly benzocyclobutenes whereas intermolecular reactions prevail in solution. The effects of sensitization and of solvent polarity suggest that benzocyclobutenes arise from singlet arylcarbenes. The amount of carbene-carbene rearrangement decreases in the order 7 (X = H) > 37 (X = CF3) > 23 (X = Me); no rearrangement was observed with 50 (X = Fl, 58 (X = SiMe(3)), and 71 (X = CMe(3)).

  CF3CH2I has been developed, demonstrating high efficiency, excellent functional‐group compatibility, especially with large sterically hindered groups. The key to success is the combination of nickel with readily available nitrogen and phosphine ligands. The powerful potential of this strategy is further demonstrated by the late‐stage modification of several derived bioactive molecules.

  已经开发出了镍与工业原料CF 3 CH 2 I催化的碘代芳基碘的直接三氟乙基化反应，显示出高效率，出色的官能团相容性，特别是对于大的位阻基团。成功的关键是镍与现成的氮和膦配体的结合。几种衍生生物活性分子的后期修饰进一步证明了该策略的强大潜力。
