  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)).

  derivatives are bench stable reagents yet can serve as benzyl anion equivalents under mild reaction conditions. Following activation with fluoride they can successfully participate in a wide range of additions to both non-enolizable and enolizable carbonyls. In addition, their use in the synthesis of isochromanones and trifluoromethylated amines is illustrated. The broad synthetic scope and mild practical

  1-alkenes, and under mild and basic reaction conditions they produce a variety of 1,2-diboronate esters with excellent conversions and chemoselectivities. The presence of bis(catecholato)diboron (B(2)cat(2)) favours the reduction of Pd(III) to Pd(II), while the catalytic precursor of Pd(II) is transformed into Pd(0)-nanoparticles. An "in situ" catalytic tandem reaction has been designed to transform the

  新型Pd（2）（6+）化合物已经以高收率合成。这些化合物及其作为合成前体的Pd（2）（4+）对应物介导乙烯基芳烃和脂肪族1-烯烃的硼酸酯化，在温和和碱性的反应条件下，它们生成具有优异转化率和化学选择性的各种1,2-二硼酸酯。双（儿茶酚）二硼（B（2）cat（2））的存在有利于将Pd（III）还原为Pd（II），而Pd（II）的催化前体转化为Pd（0）-纳米颗粒。 。设计了一种“原位”催化串联反应，将二硼酸酯中间体转化为单芳基化产物，该产物在氧化处理后可提供碳羟基化的加合物。最终，相同的催化剂完成了这两个序列，并从烯烃中完全转化。

  lithiation methodology to allylic and benzylic fluorides 1 led to the corresponding allylic and benzylic organolithium reagents, which, in the presence of different electrophiles (Barbier-type reaction conditions), afforded the expected products 2 in moderate yields. The procedure was useful for the transformation of primary, secondary and tertiary benzylic fluorides into the corresponding lithium

  Short‐lived pivaloylmetals, (H3C)3C‐COM, were established as the reactive intermediates arising through thermal heterolytic expulsion of O=CtBu2 from the overcrowded metal alkoxides tBuC(=O)‐C(‐OM)tBu2 (M=MgX, Li, K). In all three cases, this fission step is counteracted by a faster return process, as shown through the trapping of tBu‐COM by O=C(tBu)‐C(CD3)3 with formation of the deuterated starting

  短寿命的新戊酰金属（H 3 C）3 C-COM被确定为通过过度拥挤的金属醇盐t BuC（= O）-C（-OM）中O = C t Bu 2的热异质驱除而产生的反应性中间体t Bu 2（M ＝ MgX，Li，K）。在所有这三种情况下，裂变步骤都可以通过更快的返回过程来抵消，如通过O = C（t Bu）-C（CD 3）3截留t Bu-COM并形成氘代起始醇盐所示。如果在不存在捕集剂的情况下产生，则所有三个t Bu-COM物种都会“二聚化”，从而得到烯醇化物MO-C（t Bu）= C（t Bu）-OM以及O = C t Bu 2（2当量）。通过剩余O = C t Bu 2进行的共模速率降低证明存在一些自由t Bu-COM（与O = C t Bu 2分开）；但是必须假定具有未分离复合物特征的伴随中间体，例如t Bu-COM＆O = C t Bu 2。在THF中生成t Bu-COMgX的慢裂变步骤使二
