SYNTHESIS OF HYDROPHOBIC MODULUS FOR SURF ACTANTS BY ATDP MONOSALTS INTERMEDIARY OF FUNCTIONAL 1,3-DIOLS

The action of the couple hexamethylphosphorous triamide (TDAP)/carbon tetrachloride (CCl4) on the fatty amides of the 3-hydroxy-2-hydroxymet hyl-2-methyl-propionic acid leads to the corresponding alkyloxy [tris( dimethylamino) phosphonium] monosalts (ATDP salts) in the form of chlo rides, azides, and hexafluorophosphates. This reaction is applied to f atty amides containing perhydrogenated or perfluorinated chains and al so to amides prepared with compounds containing an aminoacid fatty-est er substituent. These ATDP salts are used as substrates for nucleophil ic substitution to prepare the corresponding chloro, azido or morpholi no derivatives, These compounds are potentially new hydrophobic ''synt hons'' for surfactant ''modular strategy method''.
