Reactions catalyzed within inorganic and organic materials and at electrochemical interfaces commonly occur at high coverage and in condensed media, causing turnover rates to depend strongly on interfacial structure and composition, 94-93-9, Name is 2,2′-((Ethane-1,2-diylbis(azanylylidene))bis(methanylylidene))diphenol, SMILES is OC1=CC=CC=C1C=NCCN=CC2=CC=CC=C2O, in an article , author is Chen, Ming, once mentioned of 94-93-9, SDS of cas: 94-93-9.
The development of a platinum-catalyzed desaturation of cyclic ketones to their conjugated alpha,beta-unsaturated counterparts is reported in this full article. A unique diene-platinum complex was identified to be an efficient catalyst, which enables direct metal-enolate formation. The reaction operates under mild conditions without using strong bases or acids. Good to excellent yields can be achieved for diverse and complex scaffolds. A wide range of functional groups, including those sensitive to acids, bases/nucleophiles, or palladium species, are tolerated, which represents a distinct feature from other known desaturation methods. Mechanistically, this platinum catalysis exhibits a fast and reversible alpha-deprotonation followed by a rate-determining beta-hydrogen elimination process, which is different from the prior Pd-catalyzed desaturation method. Promising preliminary enantioselective desaturation using a chiral-diene-platinum complex has also been obtained.
But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 94-93-9, you can contact me at any time and look forward to more communication. SDS of cas: 94-93-9.
