Regioselective Monoalkylation of Calixarenes. Synthesis of Homodimer Calixarenes
The Journal of Organic Chemistry, 2000The selective monoalkylation at the smaller (lower) rim of the p-tert-butylcalix[4]- and -[6]arenes using bis(butyltin)oxide and different alkylating agents is described. The procedure is remarkable for the mild conditions used allowing an efficiently access to monoalkylated calixarene derivatives in moderate to good yields.

Introduction Contributions featuring the chemistry and applications of a family of macrocyclic compounds collectively known as ‘calixarenes’ are presented in this edited volume. The arsenal of structures based on calixarenes provides tools which are effective in numerous areas of supramolecular chemistry. The Editors have compiled a timely volume which

This chapter deals with those members of the calix[n]arene family having a number n of aryl rings ranging from 7 to 20, which have been defined as the "large" calixarenes. In particular, their synthesis, chemical modification, and supramolecular properties are here reviewed. Notwithstanding their unfavorable common features (the lack of efficient large-

Deprotonation of Calixarenes in Acetonitrile
The Journal of Organic Chemistry, 2005[Structure: see text]. The pKa values for calixarenes in MeCN have been determined by selective titration with bases using a spectroscopic method. These values are as follows: calix[4]arene pKa(1) = 19.06 +/- 0.22, pKa(2) > 33; calix[6]arene pKa(1) = 15.59 +/- 0.06, pKa(2) = 23.85 +/- 0.35, pKa(3) > 33; calix[8]arene pKa(1) = 17.20 +/- 0.20, pKa(2 ...
