A set of 18 zerovalent group 8 metal complexes of the form [MLn(CO)5-n] (M=Fe, Ru, Os; L=neutral donor; n=0-2) were screened for their catalytic performance in aldehyde hydrosilylation and olefin hydroboration reactions. Although none of the untested catalysts were found to perform better than the previously-published complex [Fe(CO)4(IMes)] (IMes=1,3-Dimesityliidazol-2-ylidene), the results suggest that the Lewis basicity of the metal complex does not play a critical role in the catalysis of these two reactions.

The direct dehydrogenation of alkanes is among the most efficient ways to access valuable alkene products. Although several catalysts have been designed to promote this transformation, they have unfortunately found limited applications in fine chemical synthesis. Here, we report a conceptually novel strategy for the catalytic, intermolecular dehydrogenation of alkanes using a ruthenium catalyst. The combination of a redox-active ligand and a sterically hindered aryl radical intermediate has unleashed this novel strategy. Importantly, mechanistic investigations have been performed to provide a conceptual framework for the further development of this new catalytic dehydrogenation system.

The synthesis, characterization, and catalytic activity of low-spin {CoNO}8 pincer complexes of the type [Co(PCP)(NO)(H)] are described. These compounds are obtained either by reacting [Co(PCP)(κ2-BH4)] with NO and Et3N or, alternatively, by reacting [Co(
