  Nitration of Silyl Allenes To Form Functionalized Nitroalkenes

  摘要：

  An efficient nitration of silyl allenes with nitrogen dioxide radical, generated from NaNO2 and AcOH, to form alpha-nitro-alpha,beta-unsaturated silyl oximes has been developed. A similar nitration could be achieved by using Fe(NO3)(3)center dot 9H(2)O and FeCl3 center dot 6H(2)O, but different from the regioselective oxime formation, two regioisomeric chloride-trapped products were isolated with varying ratios depending on the steric bulk of the silyl group. A novel ring-closure reaction of alpha-nitro-alpha,beta-unsaturated silyl oximes upon treating with TBAF to form isooxazolidinone derivatives was also developed.

  Selectivity Control in Alkylidene Carbene-Mediated C−H Insertion and Allene Formation

  摘要：

  Regioselectivity of alkylidene carbene-mediated C-H insertion was explored utilizing electronic, conformational, steric, and stereoelectronic effects. Relying on these factors, highly regio- and chemoselective carbene insertion reaction of C-H bonds in different environments could be obtained. The observed selectivity clearly indicates that an electronic effect plays a more important role than steric effect. In general, C-H bonds in conformationally rigid cyclic environments are less reactive than those in acyclic systems toward carbene insertion, and in this situation, a competing intermolecular reaction between alkylidene carbene and trimethylsilyldiazomethane led to the formation of allenylsilanes. The formation of allenylsilane becomes more favorable as the concentration of reaction becomes higher, as well as the C-H bonds undergoing insertion becomes electronically and conformationally deactivated.

  involving the activation of an allenic C(sp2)H over an allylic C(sp3)H bond is described. In this ene reaction, the presence of a silyl substituent was found to be critical for the observed reactivity and selectivity since the corresponding alkyl‐substituted allenes show different reaction profiles. Computational studies show that the origin of this unusual reactivity is the lower bond dissociation

  Substituent‐ and oxidant‐dependent transformations of allenes are described. Given the profound influence of the substituent on the reactivity of allenes, the subtle differences in allene structures are manifested in the formation of diverse products when reacted with different electrophiles/oxidants. In general, reactions of nonsilylated allenes involve an allylic cation intermediate by forming a

  描述了丙二烯的取代基和氧化剂依赖性转化。考虑到取代基对丙二烯反应性的深远影响，当与不同的亲电试剂/氧化剂反应时，丙二烯结构的细微差异体现在各种产物的形成中。通常，非甲硅烷基化的丙二烯的反应通过与杂化的C2形成DD键（2,3-二氯-5,6-二氰基对苯醌）或TBHP（通过在杂化C2上形成C-O键）来涉及烯丙基阳离子中间体。叔丁基过氧化氢）中，用的FeCl沿2 ⋅4ħ 2O（10摩尔％）。相反，甲硅烷基化丙二烯青睐炔阳离子中间体的由丙二烯氢化物转移到氧化剂，从而产生1,3-烯炔（E1产品）或丙炔醚THBP（S形成Ñ 1个产物）。DFT计算强烈支持由非甲硅烷基化和甲硅烷基化的丙二烯形成这些不同的假定阳离子中间体。

  Novel oxidative dimerization of silylallenes is described. Treatment of silylallenes with a catalytic amount of copper(I) chloride, a substoichiometric amount of N-hydroxyphthalamide, and a stoichiometric amount of a terminal oxidant diacetoxyiodobenzene afforded head-to-head dimers as the main products. Silyallenes containing a small ring afforded only dimers, whereas as the ring size increased 1
