Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 554-62-1, Name is Phytosphingosine, SMILES is CCCCCCCCCCCCCC[C@@H](O)[C@@H](O)[C@@H](N)CO, belongs to chiral-catalyst compound. In a document, author is Park, Dongseong, introduce the new discover, Application In Synthesis of Phytosphingosine.
Enantioselective C(sp(2))-H borylations of diarylmethylsilanes were catalyzed using iridium complexes with chiral pyridine-dihydroisoquinoline (PyDHIQ) ligands. High enantioselectivities (up to >99% ee) were observed for various substrates. A gram-scale synthesis was achieved using 1 mol% of the catalyst to afford a 91% yield of the desired chiral borylated organosilane product with >99% ee. (C) 2020 Elsevier Ltd. All rights reserved.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 554-62-1 is helpful to your research. Application In Synthesis of Phytosphingosine.
