Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 18531-99-2, molcular formula is C20H14O2, introducing its new discovery. COA of Formula: C20H14O2
The present invention provides a novel ligand represented by the following formula and a novel transition metal complex having the ligand, which shows superior enantioselectivity and catalytic efficiency, particularly high catalyst activity, in various asymmetric synthesis reactions. A transition metal complex having, as a ligand, a compound represented by the formula wherein R4 is a hydrogen atom or a C1-6 alkyl group optionally having substituent(s), and R5 and R6 are each a C1-6 alkyl group optionally having substituent(s), or the formula is a group represented by the formula wherein ring B is a 3- to 8-membered ring optionally having substituent (s).
One of the oldest and most widely used commercial enzyme inhibitors is aspirin, COA of Formula: C20H14O2, which selectively inhibits one of the enzymes involved in the synthesis of molecules that trigger inflammation. you can also check out more blogs about 18531-99-2
