Calixarenes are cyclic oligomers obtained by condensation of suitable p-functionalized phenols with formaldehyde, usually allowing for the synthesis of the well known small calixarenes (including up to eight phenolic subunits). We report here the discovery of much larger members of this family, exhibiting sizes up to 90 phenolic subunits: the giant calixarenes. These macrocycles are obtained according to simple, easily scalable processes, in yields up to 65%. We show that the formation of these giant macrocycles is favored by an oxygen-containing-group at the para-position of the starting phenol, high concentrations of heavy alk. bases (rubidium or cesium hydroxides) and long reaction times. A mechanism is proposed to rationalize these observations. These giant macrocycles can also be obtained in the quasi-solid state, opening interesting perspectives in the field of calixarenes chem. Along with their intrinsic fundamental interest, these objects are also opening interesting applicative potentialities. This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2Quality Control of 4-Benzyloxyphenol).
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. Polyesters are important plastics, with monomers linked by ester moieties. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.Quality Control of 4-Benzyloxyphenol
