  Sodium sulfide in methanol: a two-in-one reagent for deprotection of silyl and formation of propargyl sulfide

  摘要：

  A new reagent Na2S/MeOH for silyl deprotection has been developed. The reagent has several advantages which include deprotection of C-TMS, O-TMS, O-TBS, and O-TBDPS, selective removal of C-TMS and O-TMS in the presence of O-TBS and simultaneous desilylation and sulfide formation in one pot.

  Highly atom economical uncatalysed and I2-catalysed silylation of phenols, alcohols and carbohydrates, using HMDS under solvent-free reaction conditions (SFRC)

  摘要：

  An uncatalysed silylation of phenols, regardless on the aggregate state and nature of the substituents with 0.55 equiv of HMDS under solvent-free reaction conditions (SFRC) at room temperature is reported. Sterically hindered phenols, carbohydrates and most of the alcohols additionally required a catalytic amount (up to 2 mol%) of iodine. The reaction protocol is very simple; obtaining a pure product, particularly of uncatalysed reactions, was frequently a completely solvent-free process. (C) 2012 Elsevier Ltd. All rights reserved.

• Cobalt Catalysis at the Crossroads: Cobalt-Catalyzed Alder−Ene Reaction versus [2 + 2] Cycloaddition
  作者：Gerhard Hilt、Anna Paul、Jonas Treutwein

  DOI：10.1021/ol100266u

  日期：2010.4.2

  The application of bidentate phosphine ligands in cobalt-catalyzed transformations of cyclic alkenes such as cyclopentene and cycloheptene with internal alkynes led to a chemoselective Alder−ene or a [2 + 2] cycloaddition reaction depending on the electronic nature of the alkyne and the bite angle of the ligand used.

  The palladium‐catalyzed cyclopropanation of strained alkenes with 3‐trimethylsilyl‐ or 3‐pinacolatoboryl‐1‐arylallyl acetate derivatives is described. This reaction gives cyclopropanation products in good to high yields with a single diastereomer, and the key step is likely to involve the formation of a palladacyclobutene complex from the α‐trimethylsilyl‐ or α‐pinacolatoboryl‐σ‐allylpalladium complex

  OSitBuMe₂ and OSiiPr₃ groups, other than the OSiMe₃ group, were successfully substituted. The substitution reaction of enantiopure secondary benzylic silyl ether yielded the corresponding racemic thioether product, which suggested that the reaction of tertiary alkyl, secondary alkyl, benzylic, and propargylic silyl ethers would proceed via a SN1 mechanism.

  在InI 3催化剂存在下，用硫代硅烷平稳地进行甲硅烷氧基的取代，得到相应的硫醚。在该反应体系中，InI 3是一种特别有效的催化剂，而其他典型的路易斯酸，如BF 3·OEt 2，AlCl 3和TiCl 4则无效。可使用各种甲硅烷基醚，例如伯烷基，仲烷基，叔烷基，烯丙基，苄基和炔丙基类型。另外，除OSiMe 3基团外，笨重的OSitBuMe 2和OSiiPr 3基团也被成功取代。对映体纯的仲苄基甲硅烷基醚的取代反应产生相应的外消旋硫醚产物，这表明叔烷基，仲烷基，苄基和炔丙基甲硅烷基醚的反应将通过SN1机理进行。

  日期：2009.10

  cobalt-catalysed [6+2] cycloaddition of cycloheptatriene with internal alkynes as well as with terminal alkenes is described. The cycloaddition process is most efficiently catalysed by cobalt dibromide[bis(triisopropylphosphite)] complexes in dichloromethane as the solvent of choice. In the cobalt-catalysed reaction of cycloheptatriene with norbornene an unexpected tricyclic [2+2] cycloaddition product was
