Structural conditions required for the bridge lithiation and substitution of a basic calix[4]arene
Lithiation and subsequent reaction with CO2 was applied to calix[4]arenes with different, equal or mixed, ether functions at the lower-rim site as well as tert-butylated or non-tert-butylated upper-rim positions. Whereas this reaction fails for symmetric calix[4]arene ethers with alkoxy residues gre...
