  A chemoselective method for the direct halogenation of different types of alcohols with halosilanes under catalyst- and solvent-free reaction conditions (SFRC) is reported. Various primary, secondary and tertiary benzyl alcohols and tertiary alkyl alcohols were directly transformed to the corresponding benzyl and alkyl halides, respectively, using chlorotrimethylsilane (TMSCl) and bromotrimethylsilane

  Bismaleimides (BMI) exhibit excellent heat resistance (high Tg and high resistance to thermal decomposition) compared to epoxy resins and phenolic resins, and therefore, in recent years, more attention is paid to bismaleimides as a resin material for the next-generation devices represented by SiC power semiconductors, in addition to the investigation on the use of bismaleimides for electronic material applications. As such, conventional BMI's are known as highly heat-resistant resins; however, there is a demand for a resin having higher heat resistance for advanced material applications and the like. Thus, an object of the invention is to provide a novel maleimide compound having superior heat resistance. Disclosed is a substituted or unsubstituted allyl group-containing maleimide compound having a structure with three or more benzene rings, having one or more groups each having a substituted or unsubstituted allyl group, and having one or more maleimide groups.

  development of an indirect three-step domino sequence for the formation of C-C bonds from alcohol substrates is described. An iridium-catalysed dehydrogenation of alcohol I affords the intermediate aldehyde 2. The desired C-C bond can then be formed by a facile Wittig olefination, yielding the intermediate alkene 3. In the final step the alkene is hydrogenated to afford the indirect Wittig product, the

  描述了从醇底物形成 CC 键的间接三步多米诺骨牌序列的成功开发。醇 I 的铱催化脱氢得到中间体醛 2。然后可以通过简单的 Wittig 烯化形成所需的 CC 键，产生中间体烯烃 3。在最后一步中，烯烃被氢化以提供间接的 Wittig 产物，即烷烃 4. 这个过程的关键是借氢的概念；在最初的脱氢步骤中除去的氢气被铱催化剂简单地借用。作为储氢器，催化剂促进 CC 键的形成，然后在最后一步返回借用的氢。在此，我们将详细介绍我们对底物和反应范围以及催化循环的局限性的研究。((c) Wiley-VCH Verlag GmbH & Co.
