Synthesis of new phosphonic derivatives with fluorinated chains

The synthesis of phosphonic derivatives (phosphonates and phosphonic acids) bearing fluorinated chains is presented. Such compounds with different spacers between these groups have been produced mainly by the telomerization of w-unsaturated phosphonic derivatives with fluorinated transfer agents such as mercaptans. The fluorinated phosphonates were quantitatively hydrolyzed to fluorinated phosphonic acids via two pathways: a classical one involving acids and another via silylation. Most products have been characterized by NMR and mass spectroscopy.
