An efficient and selective Cu-catalysed hydrohydrazination of terminalalkynes with parent hydrazine is reported. The methodology tolerates a broad range of functional groups, allows for the synthesis of symmetrical and...
characterization of a novel series of ring‐fused benzoxazine‐derived triazolium salts (1a–c) and their corresponding triazolylidene gold(I) complexes (2a–c). All new compounds were fully characterized by means of 1H and 13C NMR spectroscopy, elemental analyses, and mass spectroscopy and in the case of triazoliums 1a and 1b by single‐crystal X‐ray diffraction. The new triazolylidene gold complexes (2a–c)
我们报道了一系列新的环稠合苯并恶嗪衍生的三唑盐(1a–c)及其相应的三唑基亚金(I)配合物(2a–c)的合成和完整表征。通过1 H和13 C NMR光谱,元素分析和质谱对所有新化合物进行充分表征,对于三唑鎓1a和1b,则通过单晶X射线衍射对其进行充分表征。在苯炔衍生物和肼为氮源的末端炔烃的加氢胺化和氢肼化反应中,新的三唑基亚金络合物(2a–c)作为预催化剂进行了测试。

Aryldiazomethanes are converted by rhodium(II) acetate and iodorhodium(III) tetraphenylporphyrin to cis- rather than trans-1,2-diarylethylenes. Secondary aryldiazoalkanes react with rhodirum(II) acetate to give azines.

Abstract Bis (2-carbamoyl)phenyl diselenides and benzisoselenazol-3(2H)-ones, particularly ebselen, have been found as new catalysts for hydrogen peroxide oxidation of sulfides into sulfoxides, N,N-dimethylhydrazones into nitriles, and azines into carbonyl compounds.
