Applicazioni

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[1]. It was used in synthesis of new octanuclear manganese cluster[2] and hyperbranched polyethers[3].

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
