Application
1,1,1-Tris(hydroxymethyl)propane was used as hydrogen bond-donating agent during triol-promoted activation of the C-F bond of benzylic fluorides. It was used in synthesis of new octanuclear manganese cluster and hyperbranched polyethers.

Activation of the C-F bond of benzylic fluorides was achieved using 1,1,1-tris(hydroxymethyl)propane (2) as a hydrogen bond-donating agent. Investigations demonstrated that hydrogen bond-donating solvents are promoting the activation and hydrogen bond-accepting ones are hindering it. However, the reaction is best

A synthetic route to prepare acetal-protected heterobifunctional poly(ethylene glycol), allyl(1-ethoxyethoxy)-PEG-OH (allyl(EE)-PEG-OH), was successfully established using a newly synthesized initiator, trimethylolpropane allyl (1-ethoxyethoxy) ether (TMPAEEE). Heterobifunctional allyl(OH)-mPEG and heterotrifunctional allyl(OH)-PEG-alkyne were obtained, respectively, after modification from this precursor polymer. The polymers
