Chemical properties
WHITE FINE CRYSTALLINE POWDER
The Uses of 4-TERT-BUTYLCALIX[6]ARENE
Starting material for further derivatization, including halogenation, acylation, and diazo coupling.
definition
ChEBI: 5,11,17,23,29,35-hexa-tert-butylcalix[6]arene-37,38,39,40,41,42-hexol is a substituted calixarene. It derives from a hydride of a calix[6]arene.
Purification Methods
It is recrystallised from CHCl3 or CHCl3/MeOH to give a white solid from the mother liquors of the calix[8]arene preparation. The hexa-acetate (Ac2O/H2SO4) crystallises from CHCl3/MeOH with m 360-362o(dec), and the (SiMe3)6 derivative crystallises from CHCl3/MeOH with m 410-412o. Its stability in KOH-xylene is the same as for the 4-tert-butylcalix[4]arene. [Gutsche et al.J Am Chem Soc 103 3782 1981.
