✦ Synopsis

Selective Halogen-Lithium Exchange Reaction of Bromine-Substituted 25, 26,27,28-Tetrapropoxycalix(4)arene (Ia).

-The selective bromine-lithium exchange of (Ia) with either BuLi or tBuLi in THF followed by quenching of the lithiated derivatives with MeOH, D2O, Me2S2, B(OMe)3, DMF, or CO2 as electrophiles results in mono-, di-, or tetrasubstituted calix(4)arenes containing various functionalities (13 examples) such as (Ib)-(Ii).
