4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Recommanded Product: 103-16-2

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: 103-16-2Recommanded Product: 103-16-2).
