PENTA(ETHYLENE GLYCOL) DI-P-TOLUENESULFONATE Usage And Synthesis

Description

Tos-PEG6-Tos is a PEG linker containing two tosyl groups. The hydrophilic PEG spacer increases solubility in aqueous media. The tosyl group is a very good leaving group for nucleophilic substitution reactions.

Uses

Pentaethylene glycol di-p-toluenesulfonate is used in the preparation of calix[4]arenes, calix[5]arenes, and crown ethers. It is also used in the preparation of 3?-formylbenzo-18-crown-6 by undergoing coupling reaction with 2,3-dihydroxybenzaldehyde.

Uses

PENTA(ETHYLENE GLYCOL) DI-P-TOLUENESULFONATE is used to prepare calix[4]arenes,1 calix[5]arenes,2 and crown ethers.3
