  Reductive Carbonylation of Aryl Halides Employing a Two-Chamber Reactor: A Protocol for the Synthesis of Aryl Aldehydes Including ¹³C- and D-Isotope Labeling

  摘要：

  A protocol has been developed for conducting the palladium-catalyzed reductive carbonylation of aryl iodides and bromides using 9-methylfluorene-9-carbonyl chloride (COgen) as a source of externally delivered carbon monoxide in a sealed two-chamber system (COware), and potassium formate as the in situ hydride source. The method is tolerant to a wide number Of functional groups positioned on the aromatic ring, and it can be exploited for the isotope labeling of the aldehyde group. Hence, reductive carbonylations run with (13)COgen provide a facile access to C-13-labeled aromatic aldehydes, whereas with DCO2K, the aldehyde is specifically labeled with deuterium. Two examples of double isotopic labeling are also demonstrated. Finally, the method was applied to the specific carbon-13 labeling of the beta-amyloid binding compound, florbetaben.

  compounds meet DMSO, a unique platform is set up to manipulate sulfonium chemistry. A case study of oxidation of alcohols to ketones is shown herein. Crucial trifluoromethoxysulfonium is initially generated, and reacts with alcohols to give new alkoxysulfonium species via ligand exchange. Subsequent base-promoted E2 elimination gives ketones with the release of Me2S.
