Abstract

A highly selective cobalt-catalyzed hydrogermylation of alkynes has been developed using complexes with inexpensive and readily accessible triazine-based PNP ligands. This method enables the selective synthesis of (E)-β-vinylgermanes from terminal alkynes, which is compatible with both alkyl- and aryl-substituted acetylenes and the selective synthesis of (Z)-α-isomers from internal alkynes. The process is characterized by exceptional selectivity, resulting in high yields.

末端和内炔的钴驱动选择性加氢化反应

一种高选择性钴催化的炔加氢化反应已经被开发出来，该反应使用廉价且易于获得的三嗪基PNP配体配合物。该方法可从末端炔选择性合成(E)-β-乙烯基germanes，与烷基取代乙炔和芳基取代乙炔兼容，也可从内炔选择性合成(Z)-α-异构体。该工艺具有特殊的选择性，产率高。

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.
