  Twofold CH functionalization of aromatic sulfonic acids was achieved with an in situ generated ruthenium(II) catalyst. The optimized cross‐dehydrogenative alkenylation protocol proved applicable to differently substituted arenes and a variety of alkenes, including vinyl arenes, sulfones, nitriles and ketones. The robustness of the ruthenium(II) catalyst was demonstrated by the chemoselective oxidative

  用原位生成的钌（II）催化剂可实现芳香族磺酸的两倍CH功能化。事实证明，优化的交叉脱氢烯基化方法适用于不同取代的芳烃和多种烯烃，包括乙烯基芳烃，砜，腈和酮。磺酰胺和磺酰氯的化学选择性氧化烯化反应证明了钌（II）催化剂的坚固性。机理研究为可逆的乙酸盐辅助的CH钌化以及随后的烯烃插入提供了支持。

  Provided herein are methods for producing α,β-unsaturated ketones from the condensation of methyl ketones in the presence of an amine catalyst. Such amine catalysts may be supported, for example, on a silica-alumina support. Such amine catalysts may be used in the presence of an additional acid. The α,β-unsaturated ketones may be produced by dimerization and/or timerization of the methyl ketones. Such α,β-unsaturated ketones may be suitable for use in producing fuels, gasoline additives, and/or lubricants, or precursors thereof. The methyl ketones may be obtained from renewable sources, such as by the fermentation of biomass.
