Catalytic activity of copper(I) complexes supported by phenanthroline-containing catenane ligands towards a new C(sp3)-O dehydrogenative cross-coupling of phenols ROH (R = Ph, 4-(2-phenylpropan-2-yl)phenyl, 2-formyl-4-methoxyphenyl, etc.) and bromodicarbonyls R1C(O)CH(Br)C(O)R2 (R1 = Me, Ph, OBn, etc.; R2 = OEt, OMe, OtBu, OBn) is reported. As the phenanthrolines are interlocked by the strong and flexible mech. bond in the catenane, the active catalyst with an open copper coordination site can be revealed only transiently and the stable, coordinatively saturated Cu(I) pre-catalyst is quickly regenerated after substrate transformation. Compared with a control Cu(I) complex supported by non-interlocked phenanthrolines, the catenane-supported Cu(I) is highly efficient with a broad substrate scope, and can be applied in gram-scale transformations without a significant loss of the catalytic activity. This work demonstrates the advantages of the catenane ligands that provide a dynamic and responsive copper coordination sphere, highlighting the potential of the mech. bond as a design element in transition metal catalyst development. This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2HPLC of Formula: 103-16-2).
4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.HPLC of Formula: 103-16-2
