Abstract
Some O-fluoro alkyl N,N'-dialkyl isoureas are prepared by reacting fluorina ted alcohols RFCH2CH2OH with dicyclohexyl- and diisopropyl-carbodiimides. N ,N'-diisopropyl isoureas are checked as alkylation agents for amino acids a nd amines. They do not work at temperatures lower than 50 degrees C and dec ompose into urea and fluorinated olefin at higher temperatures. N,N'-diisop ropylisoureas hydrochlorides act as efficient surfactants in aqueous soluti ons.
