The synthesis of acrylate derivatives bearing a difluorophosphonic acid function has been realized by ring-opening reaction of oxac-ycles and alkylation of fluorinated carbanions. Their use in self-etch adhesives is reported. The resulting adhesives based on difluorophosphonic acid monomers provide significantly higher dentin shear bond strength (SBS) than the one based on phosphonic acid, mainly due to the presence of fluorine atoms.
