Abstract
Catalytic cleavage of C—S bonds is an important approach in the construction of functionalized molecules. Herein, we developed the catalytic synthesis of nitriles from thioethers, utilizing CO2 as the carbon source for the first time. This work addressed the challenge of avoiding toxic cyanides by generating the “CN” group via isocyanate intermediates from CO2 and NH3 with the aid of Ni-phosphine catalysts and hydrosilane. A wide range of aryl thioethers were efficiently converted into the corresponding aryl nitriles, demonstrating good functional groups tolerance including fluorine, morpholine, piperazine amide, and cyano group. Additionally, chloride anion played essential roles probably through facilitating the generation of Ni (I) species by promoting Ni—S bond cleavage, thus enhancing the overall reaction efficiency.
期刊介绍：
The Journal of Catalysis publishes scholarly articles on both heterogeneous and homogeneous catalysis, covering a wide range of chemical transformations. These include various types of catalysis, such as those mediated by photons, plasmons, and electrons. The focus of the studies is to understand the relationship between catalytic function and the underlying chemical properties of surfaces and metal complexes.
The articles in the journal offer innovative concepts and explore the synthesis and kinetics of inorganic solids and homogeneous complexes. Furthermore, they discuss spectroscopic techniques for characterizing catalysts, investigate the interaction of probes and reacting species with catalysts, and employ theoretical methods.
The research presented in the journal should have direct relevance to the field of catalytic processes, addressing either fundamental aspects or applications of catalysis.
