4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. 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

Rh(I)-Diene-Catalyzed Addition of (Hetero)aryl Functionality to 1,3-Dienylsulfonyl Fluorides Achieving Exclusive Regioselectivity and High Enantioselectivity: Generality and Mechanism was written by Moku, Balakrishna;Fang, Wan-Yin;Leng, Jing;Kantchev, Eric Assen B.;Qin, Hua-Li.

Exclusively regioselective addition of (hetero)aromatic groups to 1,3-dienylsulfonyl fluorides using the Rh(I)/diene catalyst produces a class of (E)-2-aryl-4-(aryl or alkyl)but-3-ene-1-sulfonyl fluorides in high isolated yields (up to 96%) across a broad substrate scope (44 examples) indicative of high functional group tolerance. A typical dienesulfonyl fluoride showed higher activity than an analogous dienone. DFT calculations (IEFPCM/PBE0/DGDZVP level of theory) on the selectivity-determining step are in full agreement (including accurate quantification of regioisomer ratios within the computational error) with the enhanced activity and selectivity of the dienesulfonyl fluorides. The origin of this enhancement was elucidated by QTAIM to most likely arise from higher electrostatic stabilization for the more polarizable dienesulfonyl fluoride due to the significant ionic character of the Rh-Cα/Cγ bond in the immediate nonconjugated 1,4-arylation product. The use of a C1-sym. bicyclo[2.2.2]octa-2,5-diene carrying a bulky 2,6-dimethylphenyl ester residue resulted in moderate to good yields (32-64%) together with up to 98% ee for both d-aryl- and alkyl-substituted buta-1,3-diene sulfonyl fluorides. This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2Recommanded Product: 103-16-2).
