  oxidative cleavage of Passerini and Ugi adducts in the presence of base and copper(I) iodide is studied in detail. The oxidative cleavage yields α-ketoamides along with acids and amides from Passerini and Ugi adducts respectively. Mechanistic investigations revealed that the reaction proceeds via a radical pathway involving molecular oxygen. Control experiments with 18O-labeled Passerini adducts confirmed

  详细研究了存在碱和碘化铜（I）的Passerini和Ugi加合物的好氧氧化裂解。氧化裂解产生α-酮酰胺，以及来自Passerini和Ugi加合物的酸和酰胺。机理研究表明，该反应通过涉及分子氧的自由基途径进行。用18个O标记的Passerini加合物进行的对照实验证实，分子氧是α-酮酰胺中氧的来源。研究了各种Passerini和Ugi加合物，以探讨取代的影响。总的来说，本研究提供了对强碱性条件下Passerini和Ugi加合物的反应性的认识，以及制备α-酮酰胺的方法。

  The versatility of a Bedford-type palladacycle 1, namely [Pd(µ-Cl)κ2-P,C-P(OC6H2-2,4-tBu2)(OC6H3-2,4-tBu2)2}}2], as a primary Pd source, in combination with the ligand bis-1,1′-(diphenylphosphino)ferrocene (dppf) has been established in carbonylation reactions of aryl and heteroaryl bromides with methanol, piperidine and related nucleophiles. Palladacycle 1 has been compared with other primary Pd sources, e.g. (PhCN)2PdCl2 and Pd(OAc)2. The efficacy of the carbonylation processes appear to be linked to the [Pd] concentration, substrate : catalyst ratio, CO pressure and reaction temperature. In amidocarbonylation, double carbonylation is observed for certain organohalides. In the case of 2,5-dibromopyridine, regioselective amination (Hartwig–Buchwald type) also occurs as a side-reaction.

  一种Bedford型钯环化合物1，即[Pd(µ-Cl)κ2-P,C-P(OC6H2-2,4-tBu2)(OC6H3-2,4-tBu2)2}}2]，作为主要的钯源，其多功能性已在与醇、哌啶及相关亲核试剂的芳基和杂芳基溴化物的羰基化反应中得到证实。钯环化合物1已与其他主要的钯源进行比较，例如(PhCN)2PdCl2和Pd(OAc)2。羰基化过程的有效性似乎与[钯]浓度、底物与催化剂的比例、一氧化碳压力和反应温度有关。在胺羰基化过程中，某些有机卤化物观察到了双羰基化现象。在2,5-二溴吡啶的情况下，还发生了区域选择性氨基化（Hartwig–Buchwald型）的副反应。

  An efficient and chemoselective C(sp(2))-N bond cleavage of aromatic imidazo[1,2-a]pyridine molecules is developed. A broad scope of amide compounds such as alpha-ketoamides and N-(pyridin-2-yl)arylamides are afforded as the final products in up to quantitative yields. Diverse C-N bond cleavages are controlled by the oxidative species used in this transformation, with various amide products afforded in a chemoselective fashion. A preliminary study indicated that some alpha-ketoamides exhibit anti-Tobacco Mosaic Virus activity for potential use in plant protection.
