Li, Wei published the artcileHighly efficient hydrogenation of biomass-derived levulinic acid to γ-valerolactone catalyzed by iridium pincer complexes, Application In Synthesis of 338800-13-8, the publication is Green Chemistry (2012), 14(9), 2388-2390, database is CAplus.
A highly efficient catalytic method for hydrogenation of biomass-derived levulinic acid has been developed and the iridium trihydride complexes of PNP pincer ligands were found to be extremely active catalysts for this transformation, providing γ-valerolactone in high yields with TONs as high as 71 000.
Green Chemistry 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 C23H43NP2, Application In Synthesis of 338800-13-8.
