Nucleophilic fluorination of alkoxysilane with alkali metal hexafluorophosphate 1 - part 1

Article abstract of DOI:10.1016/S0022-1139(97)00112-7

Alkali metal hexafluorophosphates were used to effect nucleophilic fluorination of a few selected alkoxysilanes both in the presence and absence of polar solvents. Near-quantitative yields of fluorinated silanes were obtained using both alkoxy-equivalent of the complex salt and fluoride equivalents of alkoxysilanes. Some of the intermediate fluorosilanes and fluorophosphorus compounds were identified and the mechanism of fluorination is proposed.
