A novel phosphonium-type condensing reagent, 1,3-dimethyl-2-(3-nitro-1,2,4-triazol-1-yl)-2-pyrrolidin-1-yl-1,3,2-diazaphospholidinium hexafluorophosphate (MNTP), was designed and synthesized. A 31P NMR study on the condensation reactions of phosphate, alkylphosphonate, boranophosphate, and H-phosphonate derivatives with an alcohol in the presence of MNTP demonstrated the versatility and the enhanced activity of the new condensing reagent, compared to the previously reported phosphonium-type condensing reagents. The mechanism of the condensation reactions mediated by MNTP is discussed on the basis of the 31P NMR studies and theoretical calculations.
