Application

DMPU-HF Reagent is a nucleophilic fluorination reagent that can be used:       
  • To prepare fluoroalkenes and gem-difluoromethlylene from substituted alkynes in the presence of an Au-JohnPhos complex as a catalyst.      
  • To synthesize substituted 4-fluorotetrahydropyrans and 4-fluoropiperidines from homoallylic alcohol/amine with aldehyde via fluoro-Prins reaction.       
  • In the bromofluorination of alkenes in the presence of N-bromosuccinimide to yield corresponding bromofluoro compounds.

DMPU-HF, like TREAT-HF and Olah′s Reagent, is a convenient way of utilizing Hydrogen Fluoride as a fluorination reagent. However, unlike TREAT-HF and Olah′s Reagent, DMPU-HF is more tolerant of transition metals due to the reduced basicity of DMPU, compared to Triethylamine and Pyridine. Hammond and coworkers display its compatibility in transition-metal catalysis in gold-catalyzed mono- and difluoroination of alkynes.

Bromofluorination reactions were performed by treating of a variety of unsaturated compounds with N-bromosuccinimide (NBS) and DMPU/HF as the fluorinating reagent. The DMPU/HF complex showed to be an efficient fluorinating reagent to convert alkenes into their corresponding bromofluoro compounds. It

Hydrogen fluoride (HF) and selected nonbasic and weakly coordinating (toward cationic metal) hydrogen-bond acceptors (e.g., DMPU) can form stable complexes through hydrogen bonding. The DMPU/HF complex is a new nucleophilic fluorination reagent that has high acidity and is compatible with

DMPU/HF (HF content 65 wt %/wt) is an ideal nucleophilic fluorination reagent for the diastereoselective synthesis of substituted 4-fluorotetrahydropyrans and 4-fluoropiperidines via a fluoro-Prins reaction. When compared to classical nucleophilic fluorination reagents like pyridine/HF, DMPU/HF gives both higher yields and
