Cobalt Nanoparticles Formed upon Reaction of Cp*Co(III) Metallacycles with Na[BHEt3] Show Catalytic Activity in the Hydrosilylation of Aryl Ketones, Aldehydes and Nitriles

open access: yesEuropean Journal of Inorganic Chemistry, Volume 26, Issue 6, February 17, 2023., 2023
The treatment of a cobaltacycle with Na[BHEt3] produces Co nanoparticles that are active as catalyst for the hydrosilylation of aromatic aldehydes, ketones and nitriles. Abstract The reactivity of the 2‐phenylpyridine‐derived [Cp*CoI(phpy‐κC,N)] metallacycle towards Et3SiH and hydrides was evaluated.

Toxicity, Antibacterial, and Phytochemical Analyses of Antrocaryon klaineanum Pierre Extracts

open access: yesAdvances in Pharmacological and Pharmaceutical Sciences, Volume 2023, Issue 1, 2023., 2023
Medicinal plants are traditionally used in Gabon to treat several types of illnesses. The study’s purpose was to determine the toxic, antibacterial, and anti‐inflammatory effects of Antrocaryon klaineanum Pierre extracts and to characterize their phytochemical compounds. Toxicity was evaluated on frog tadpoles (Phrynobatrachus africanus Hallowell). The
