Azides are readily converted into their corresponding amines using a catalytic amount of Co2(CO)8 under mild conditions. The method is highly chemoselective and compatible with a variety of functionalities such as halides, esters, acids, ethers, nitro, cyano and olefinic double bonds present in the molecule.
Self-assembled multilayer iron(0) nanoparticles (NPs, 6–10 nm), namely, sulfur-modified Au-supported Fe(0) [SAFe(0)], were developed for ligand-free one-pot carbon–carbon/carbon–nitrogen bond-formingreactions. SAFe(0) was successfully prepared using a well-established metal–nanoparticle catalyst preparative protocol by simultaneous in situ metal NP and nanospace organization (PSSO) with 1,4-bis(trimethylsilyl)-1

the synthesis of this new heterocyclic scaffold is an intramolecular cyclization via an unprecedented carbonylativeC–H functionalization of 1‐(2‐bromoaryl)‐1,2,3‐triazoles. Isotopic labelling of the carbonyl carbon atom is possible using near stoichiometric amounts of 13CO. Additionally, an alternative pathway via carbonylative Sonogashira coupling followed by a two‐step, one‐pot azidation/cycloaddition
这项研究提出了4 H- [1,2,3]三唑[1,5 - a ]吲哚-4-酮的合成。合成这种新型杂环骨架的关键步骤是通过空前的1-(2-溴芳基)-1,2,3-三唑的羰基化CH功能将分子内环化。可以使用接近化学计量的13 CO进行羰基碳原子的同位素标记。此外,还研究了通过羰基Sonogashira偶联然后进行两步单罐叠氮化/环加成反应的替代途径,从而产生了相同的骨架。
