  Sustainable Oxidations: An oxidation method to transform aryl(di)azinylmethanes into aryl(di)azinyl ketones is described. Base metals (copper and iron) as catalysts in combination with O2 as the oxidant are used, which makes this method sustainable. The utility of this method is illustrated by the synthesis of 6‐(4‐methylbenzoyl)pyridine‐2‐carbaldehyde, which is an intermediate in the preparation of

  available Cp*Mo(II)-complexes as efficient deoxygenation catalysts that could catalyze the direct intermolecular deoxygenative coupling of carbonyl compounds with alkynes. Enabled by this powerful Cp*Mo(II)-catalyst, various valuable heteroarenes (10 different classes) were obtained in generally good yields and remarkable chemo- and regioselectivities. Mechanistic studies suggested that this reaction might

  羰基易于接近，是化学合成中重要的官能团。然而，由于需要高活化能来裂解强C=O双键，因此通过假定的金属卡宾中间体对羰基化合物进行直接催化脱氧官能化是一项艰巨的挑战。在这里，我们报道了一类工作台稳定且易于获得的 Cp*Mo(II) 配合物作为有效的脱氧催化剂，可以催化羰基化合物与炔烃的直接分子间脱氧偶联。在这种强大的 Cp*Mo(II) 催化剂的支持下，获得了各种有价值的杂芳烃（10 种不同类别），收率普遍良好，并且具有显着的化学和区域选择性。机理研究表明，该反应可能通过一系列C=O双键断裂、卡宾-炔复分解、环化和芳构化过程进行。该策略不仅为杂芳烃的快速制备提供了通用的催化平台，而且为Cp*Mo(II)催化剂在有机合成中的应用打开了新的窗口。
• Synergistic H₄NI–AcOH Catalyzed Oxidation of the C_sp³–H Bonds of Benzylpyridines with Molecular Oxygen

  The oxidation of benzylpyridines forming benzoylpyridines was achieved based on a synergistic H4NI-AcOH catalyst and molecular oxygen in high yield under solvent-free conditions. This is the first nonmetallic catalytic system for this oxidation transformation using molecular oxygen as the oxidant. The catalytic system has a wide scope of substrates and excellent chemoselectivity, and this procedure can also be scaled up. The study of a preliminary reaction mechanism demonstrated that the oxidation of the C-sp(3)-H bonds of benzylpyridines was promoted by the pyridinium salts formed by AcOH and benzylpyridines. The synergistic effect of H4NI-AcOH was also demonstrated by control experiments.

  N-Alkyl-N'-cyano-N"-(substituted phenyl-pyridinylmethyl) guanidine derivatives were synthesized and tested for inhibitory activity against gastric secretion in rats. Several of the compounds synthesized showed an inhibiting activity as potent as that of cimetidine against basal gastric secretion but showed less potent activity than cimetidine against histamine-stimulated gastric secretion. Some structure-activity relationships are discussed.
