Transition-Metal-Free Electrophilic Amination of Arylboroxines
摘要:
A transition-metal-free strategy to construct C(sp(2))-N bonds using arylboroxines and O-benzoyl hydroxylamines as coupling partners has been developed. This transformation provides a useful method to access various aromatic amines.
Nano CoCuFe<sub>2</sub>O<sub>4</sub>-catalyzed coupling reaction of arylboronic acid with amines and thiols: An atom-economic and ligand-free route to access unsymmetrical amines and sulfides
CoCuFe2O4‐catalyzed C‐N and C‐S bond formation. By this catalytic system, both amine and sulfide‐based structural motifs were formed efficiently in aryl halide‐free route. The amination reaction of phenyl boronic acid with various types of amines was conducted under ligand‐free conditions, in ethanol as a green solvent at 60°C. Unsymmetrical diaryl/aryl alkyl sulfide synthesis via the coupling reaction
针对纳米CoCuFe 2 O 4催化的C-N和C-S键的形成,开发了一种有效的方案。通过这种催化体系,胺和硫化物的结构基序都可以在无芳基卤化物的途径中有效地形成。苯硼酸与各种类型的胺的胺化反应是在无配体的条件下于60°C在乙醇中作为绿色溶剂进行的。还通过芳基硼酸与硫醇的偶联反应进行不对称的二芳基/芳基烷基硫化物的合成。纳米钴铜铁氧体被用作一种异质高效,廉价,可磁分离和可回收的催化剂,可用于数个循环。
