Summary: The search for an activator for the catalyst precursor [Co(tpy)Br-2] in the hydrosilylation of olefins with hydrosilane led to the discovery of K2CO3 as an effective activator. The ability of various salts to activate the catalyst was examined and compared, and it was determined that an excellent activator requires low MX lattice energy, high X-nucleophilicity, and a strong Si-X bond.

Summary: The Lewis acid-base pairs (LPs) at the interface of Cu/CeO2 catalyst exhibit excellent catalytic performance on the hydrogen borrowing reaction. LPs consist of Lewis acidic Cu(I) and Lewis basic surface oxygen (Osurf). The Cu(I)-H and Osurf-H intermediates are generated and preferentially transfer to C@N bonds instead of forming H2 molecules, leading to outstanding selectivity towards N-alkyl amine.

Summary: A feasible hydrogen storage and release process has been reported, which involves the interconversion of readily available (bi)carbonate and formate salts in the presence of naturally occurring alpha-amino acids. These transformations are of interest for the concept of circular carbon economy, and it is the first time that the use of inorganic carbonate salts for hydrogen storage and release has been described. Hydrogenation of the substrates with specific manganese pincer catalysts and glutamic acid yields high formate yields. Based on this, cyclic hydrogen storage and release processes with carbonate salts can achieve good H2 yields.
