General description
Diethylaminomethyl-polystyrene is a basic ion exchange polymer supported triethlamine resin. It may be used as dehyrohalogenating agent. NMR residue solutions can be dissolved in methanol and passed through a bed of diethylaminomethyl-polystyrene to purify the filtrate.
Application
- Diethylaminomethyl-polystyrene is designed to be used in place of the equivalent free base, to facilitate purification.
- Diethylaminomethyl-polystyrene may be used in conjunction with other solid supported reagents or catalysts to promote a reaction.
- Diethylaminomethyl-polystyrene may be used in separation media for TLC, paper and LPL chromatography.

Two different protocols for the preparation of water-soluble, enantiomerically pure polyhydroxybisphospholanes from acid-labile acetal and tert-butyldimethylsilyl-protected derivatives are reported. These procedures circumvent two of the commonly encountered limitations in the synthesis of these potentially important ligands: (a) formation of phosphonium
