les, 2, have been prepared by two different methods. Reaction of bromo-2,1,3-benzothiadiazoles, 1, with cuprous cyanide occurs advantageously in refluxing dimethylformamide to give 2, complexed with curpous bromide. Hydrogen peroxide in hydrochloric acid at 30–40° is shown to be an effective reagent for efficient decomposition of these reactions complexes, 2 CuBr, and subsequent isolation of 2. Yields

Silyl, germyl, stannyl radicals have been reacted with a variety of ring substituted benzo[2,1,3]thiadiazoles, and the paramagnetic adducts resulting from addtion to one of the heterocyclic nitrogens have been characterized by means of ESR spectroscopy. Reactions with unsymmetrically substituted substrates lead to the formation of two distinct isomeric adducts, whose relative amounts depend on the

compounds are indispensable chemicals widely used in basic and applied sciences. Among these, especially aromatic aldehydes, ketones, carboxylic acids, esters, nitriles, and amides represent valuable fine and bulk chemicals, which are used in chemical, pharmaceutical, agrochemical, and material industries. For their synthesis, catalytic aerobic oxidation of alcohols constitutes a green, sustainable, and cost-effective
功能化(杂)芳族化合物是基础和应用科学中广泛使用的不可或缺的化学品。其中,尤其是芳香醛、酮、羧酸、酯、腈和酰胺是有价值的精细和大宗化学品,可用于化学、制药、农业化学和材料工业。对于它们的合成,醇的催化有氧氧化构成了一种绿色、可持续且具有成本效益的工艺,理想情况下应该利用活性和选择性的 3D 金属。在这里,我们报告了通过在碳上热解钴-哌嗪-酒石酸络合物作为最通用的氧化催化剂,制备包裹在 Co-纳米颗粒中的石墨层。这种独特的材料可以合成简单、功能化和结构多样的(杂)芳香醛、酮、
