DIETHYLENE GLYCOL BIS(P-TOLUENESULFONATE) Usage And Synthesis
Description
Tos-PEG3-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.
Chemical Properties
White to off-white powder
Uses
Diethylene glycol di(p-toluenesulfonate) was used in the synthesis of bis(dibenzosulfoxo)-27,30,35,38-tetramethyl-24-crown-6, bis(dibenzosulfoxo)-21,24,29,32-tetramethyl-18-crown-4, dibenzosulfoxo-15,18-dimethyl-12-crown-3 and dibenzosulfoxo-12,15-dimethyl-9-crown-2 macrocycles.
Purification Methods
Purify the ester by recrystallisation from Me2CO and dry it in a vacuum. [Beilstein 11 III 225.]
