  The previously observed cyclopropaoation of alkenes by irradiation of diiodomethane (I) in their presence has been studied in more detail and found to be a synthetically useful procedure which is significantly less subject to steric effects than the traditional Simmons-Smith method. The results from photocyclopropanation of a variety of alkenes are summarized in Tables 1 and 3–4. In a number of cases

  先前观察到的通过二碘甲烷的辐射对烯烃的环丙烷化反应（I）的存在，我们对其进行了更详细的研究，发现它是一种合成上有用的方法，与传统的Simmons-Smith方法相比，其受到的空间位阻明显更少。表1和表3-4汇总了各种烯烃的光环丙烷化结果。在许多情况下，光化学程序提供的结果优于Simmons-Smith方法，尤其是使用空间拥挤的烯烃时。环烯烃显示的光环丙烷化相对速率是环大小的函数，类似于Simmons-Smith方法（表5）。然而，与Simmons-Smith方法相比，光环丙烷化反应的相对速率随着双键取代度的增加而稳定增加（表6），其中空间效应抵消了随着取代作用的增加烯烃的亲核性的提高。α碘化建议使用2作为亚甲基转移物质。在溴化锂存在下，将阳离子2捕集，得到溴碘甲烷。

  The sequential installation of a carbenoid and a hydride into a carbonyl, furnishing halomethyl alkyl derivatives, is reported. Despite the employment of carbenoids as nucleophiles in reactions with carbon-centered electrophiles, sp3-type alkyl halides remain elusive materials for selective one-carbon homologations. Our tactic levers on using carbonyls as starting materials and enables uniformly high

  据报道，将类胡萝卜素和氢化物顺序安装在羰基上，提供了卤代甲基烷基衍生物。尽管在与以碳为中心的亲电子试剂的反应中使用类胡萝卜素作为亲核试剂，sp 3型烷基卤化物仍然是用于选择性一碳同系物的难以捉摸的材料。我们的策略是利用羰基化合物作为起始原料，从而能够均匀地实现高收率和化学控制。该策略是灵活的，不仅限于类胡萝卜素。而且，各种类似碳负离子的物种可以充当亲核试剂，因此使其具有普遍的适用性。
• A Straightforward Homologation of Carbon Dioxide with Magnesium Carbenoids en Route to α-Halocarboxylic Acids

  homologation of carbon dioxide with stable, (enantiopure) magnesium carbenoids constitutes a valuable method for preparing α‐halo acid derivatives. The tactic features a high level of chemocontrol, thus enabling the synthesis of variously functionalized analogues. The flexibility to generate magnesium carbenoids through sulfoxide‐, halogen‐ or proton‐ Mg exchange accounts for the wide scope of the reaction.

  for the direct hydrofluoromethylation of alkenes is reported for the first time. This straighforward silyl radical-mediated reaction utilises CH2FI as a non-ozone depleting reagent, traditionally used in electrophilic, nucleophilic and carbene-type chemistry, but not as a CH2F radical source. By circumventing the challenges associated with the high reduction potential of CH2FI being closer to CH3I than

  首次报道了烯烃直接氢氟甲基化的方法。这种直接的甲硅烷基自由基介导的反应利用 CH 2 FI 作为非臭氧消耗试剂，传统上用于亲电、亲核和卡宾型化学，但不作为 CH 2 F 自由基源。通过规避与 CH 2 FI的高还原电位比 CF 3 I更接近 CH 3 I相关的挑战，并利用 C-I 键的有利键解离能，我们证明了原料缺电子烯烃被转化在 (Me 3 Si) 3的干预下，由净氢氟甲基化产生的产物蓝色 LED 激活下的 SiH。这种看似简单但功能强大的方法已扩展到一系列（卤）甲基自由基前体，包括 ICH 2 I、ICH 2 Br、ICH 2 Cl 和 CHBr 2 F，以及 CH 3 I 本身；因此后一种试剂能够直接加氢甲基化。这种多功能化学被应用于18 F-、13 C- 和 D- 标记的试剂以及复杂的生物相关烯烃，为药物化学和正电子发射断层扫描中的应用提供了五十多种产品。
