Triphenylphosphine in reactions with ω-haloalkylcarboxylic acids

GRAPHICAL ABSTRACT

ABSTRACT

Stable phosphonium salts were synthesized by the phosphorylation of a series of ω-haloalkylcarboxylic acids with triphenylphosphine. In a second step the resulting phosphonium salts have been treated with 1 M aqueous solution of sodium hydroxide to form the corresponding carboxylate phosphabetaines. The structure of the isolated compounds was determined by IR and NMR spectroscopy, elemental analysis, and X-ray crystallographic studies. Their thermal stability was studied by simultaneous thermogravimetry and differential scanning calorimetry.
