Tanaka, Ryo published the artcileCatalytic Hydrogenation of Carbon Dioxide Using Ir(III)-Pincer Complexes, Recommanded Product: 2,6-Bis((di-tert-butylphosphino)methyl)pyridine, the publication is Journal of the American Chemical Society (2009), 131(40), 14168-14169, database is CAplus and MEDLINE.
Catalytic hydrogenation of carbon dioxide in aqueous potassium hydroxide was performed using a newly synthesized isopropyl-substituted PNP-pincer iridium trihydride complex as catalyst. Potassium formate was obtained with turnover number up to 3,500,000 and turnover frequency of 150,000 h-1.
Journal of the American Chemical Society published new progress about 338800-13-8. 338800-13-8 belongs to pyridine-derivatives, auxiliary class Bis-phosphine Ligands, name is 2,6-Bis((di-tert-butylphosphino)methyl)pyridine, and the molecular formula is C7H13BrSi, Recommanded Product: 2,6-Bis((di-tert-butylphosphino)methyl)pyridine.
