In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called N-Heterocarbene Palladium Complexes with Dianisole Backbones: Synthesis, Structure, and Catalysis, published in 2019-06-24, which mentions a compound: 49609-84-9, mainly applied to heterocarbene palladium complex dianisole preparation Suzuki coupling catalyst; crystal structure mol palladium complex dianisole heterocyclic carbene preparation, Formula: C6H3Cl2NO.
A series of palladium N-heterocyclic carbenes (NHCs), complexes C1-C5, bearing dianisole backbones and substituted N-aryl moieties have been synthesized and characterized. The electronic effect as well as the steric environment of the NHC ligands has been assessed. The synthesized palladium complexes were applied for Suzuki-Miyaura cross-coupling reactions under aerobic conditions. The relationship between the catalytic structure and catalytic performance was then extensively investigated. Upon optimizing the reaction conditions, the C4 was found to be highly efficient to catalyze the cross-coupling of (hetero)aryl chlorides with (hetero)arylboronic acids at a 0.1 mol % palladium loading.
After consulting a lot of data, we found that this compound(49609-84-9)Formula: C6H3Cl2NO can be used in many types of reactions. And in most cases, this compound has more advantages.
