The rapidly prepared 1,3‐diaminobenzene‐derived aminophosphine pincer complex C6H3[NHP(piperidinyl)2]2Pd(Cl)} (1) is an effective Suzuki catalyst with excellentfunctionalgrouptolerance. Side‐product formations, such as homocoupling, debromation or protodeboration have only rarely been detected and if so, were in all cases below the 5% level. The presented reaction protocol is universally applicable
快速制备的1,3-二氨基苯衍生的氨基膦钳形配合物C 6 H 3 [NHP(哌啶基)2 ] 2 Pd(Cl)}(1)是一种有效的Suzuki催化剂,具有出色的官能团耐受性。仅很少检测到副产物形成,例如均偶联,去溴化或原去硼,如果这样,在所有情况下均低于5%的水平。提出的反应方案是普遍适用的。实验观察表明,钯纳米颗粒的催化活性形式1。
Nickel-Mediated Decarbonylation of Simple Unstrained Ketones through the Cleavage of Carbon–Carbon Bonds
decarbonylation of ketones has been met with limited success because this process requires the activation of two inert carbon-carbon bonds. All of the decarbonylation reactions of simple unstrainedketones reported to date require the addition of a stoichiometric rhodium complex. We report herein the nickel/N-heterocyclic carbene-mediated decarbonylation of simple diaryl ketones. This reaction shows
