Synthesis of polyfunctional phosphorus-containing calixarenes in cycloaddition reactions of azides to alkynes

Metallocalix[n]arenes in catalysis: A 13-year update

“…Moreover, one of the branched products was also shown to undergo selective hydrogenation affording its lactone derivative. With respect to tests performed in other protic solvents, Vatsouro et al recently described the synthesis of the polyfunctional phosphorus-containing calixarenes 89 and 90 (Figure 23) and their use as ligands in the olefin hydroformylation in ethanol [90]. In this case, [Rh(cod) 2 ]BF 4 (cod = cyclooctadiene) was selected as metal precursor.…”

Novel oxadiazole- and triazole-based calixarene derivatives: synthesis and extraction properties

“…The phenolic hydroxyl groups and the para positions of calixarenes can easily be functionalized to obtain molecules with desired sizes [1][2][3][4][5]. In addition, the meta positions and the methylene bridges can also be functionalized [6][7][8][9].…”
