Enhanced etherification of calix[4]arenes by microwave irradiation
Xu, Zhen,Lü, Zao Sheng,Chen, Lei
, p. 77 - 83 (2017/05/12)
Microwave irradiation has been found to be a highly efficient method for etherification of p-tert-butylcalix[4]arene with alkyl bromides or ditosylate. The corresponding products were obtained as a pure form in modest yield within short reaction time when
Synthesis of a cone-conformer bimodal calix[4]arene-crown-5 which forms a sensitive cesium ion sensing layer on gold-coated microcantilevers

A "bimodal" or upper- and lower-rim functionalized "calix-crown-5" reported herein was unexpectedly formed preferentially in a cone conformation. This was confirmed both by NMR spectroscopy and by single-crystal X-ray crystallography. The thioacetate functionalities on the new calix-crown-5 enabled it to form stable SAMs on the Au surface of a microcantilever, and a sensitive cesium ion sensor. This journal is
Facile synthesis of cone p-tert-butylcalix[4]arene-crown conformers
Alekseeva, Elena A.,Basok, Stepan S.,Mazepa, Alexander V.,Gren, Andrei I.
, p. 330 - 331 (2008/03/30)
The series of p-tert-butylcalix[4]arene-crowns in the cone conformation was synthesised in high yields under conditions producing disubstituted calix[4]arenes in the presence of K2CO3 in acetonitrile; the formation of calix-bis(crown)s and doubly(calix)-doubly(crown) in these reactions was established.
