Regioselective monoalkylation of calixarenes. Synthesis of homodimer calixarenes

The 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. Monoalkynylcalix[4]arene and monoalkynylcalix[6]arene have been synthetically exploited for the synthesis of bis-calix[n]arenes (n = 4, 6) with a diyne bridge by oxidative coupling of alkynes. In addition, intermolecular methathesis of the obtained monoalkenylcalix[4]arene allowed the preparation of bis-calix[4]arene that are single bridged at the smaller (lower) rim with a 2-butenyl moiety.

Easy and selective method for the synthesis of Mono-, di-, tri-, tetra-O-arylmethyl-p-t-butylcalix[4]arenes

Mono-, di-, tri- and tetra-O-arylmethyl-p-t-butylcalix[4]arenes were synthesised respectively from p-t-butylcalix[4]arene and arylmethyl bromide through an easy and selective one-step reaction. Mono- and di-arylmethyl ethers of p-t-butylcalix[4]arenes wer

Multinuclear calixarene synthons with covalently linked aryl-palladium(II) complexes

New synthetic procedures have been developed for potentially useful metallacalixarene building blocks. The metal sites were covalently connected to calix[n]arenes (n = 4, 6) by oxidative addition of 4-iodobenzyl precursors to either Pd(PPh3)su

Unexpected Single-Step Formation of 1,2-anti-Heterodisubstituted Calix[4]arenes upon Alkylation of a Tribenzoyl Precursor

The selective preparation and complete structural characterization of a small series of 1,2-anti-hetero-disubstituted calix[4]arenes has been accomplished. These compounds were obtained in two steps from unsubstituted p-tert-butylcalix[4]arene by tribenzo
