  日期：2003.10.1

  A single method (2% Pd(2)(dba)(3)/8% PCyp(3)/NMI in THF/NMP at 80 degrees C; Cyp = cyclopentyl) achieves the cross-coupling of a range of beta-hydrogen-containing primary alkyl iodides, bromides, chlorides, and tosylates with an array of alkyl-, alkenyl-, and arylzinc halides. The process is compatible with a variety of functional groups, including esters, amides, imides, nitriles, and heterocycles

• Highly nucleophilic vitamin B₁₂-assisted nickel-catalysed reductive coupling of aryl halides and non-activated alkyl tosylates
  作者：Kimihiro Komeyama、Ryo Ohata、Shinnosuke Kiguchi、Itaru Osaka

  DOI：10.1039/c7cc01932g

  日期：——

  Reductive cross-coupling of aryl halides with ubiquitous alkyl tosylates was developed using a combination of nickel and vitamin B12 catalysts. The tosylate was activated by reduced vitamin B12 to form alkyl cobalt(III) which served as a good alkylating agent for aryl-nickel species, leading to the C(sp3)–C(sp2) bond formation.

  使用镍和维生素B 12催化剂的组合开发了芳基卤化物与无处不在的烷基甲苯磺酸盐的还原性交叉偶联反应。甲苯磺酸盐通过还原的维生素B 12活化而形成烷基钴（III），该烷基钴可作为芳基镍物种的良好烷基化剂，从而导致C（sp 3）–C（sp 2）键的形成。
