ملخص: Some O-fluoro alkyl N,N′-dialkyl isoureas are prepared by reacting fluorinated alcohols RFCH2CH2OH with dicyclohexyl- and diisopropyl-carbodiimides. N,N′-diisopropyl isoureas are checked as alkylation agents for amino acids and amines. They do not work at temperatures lower than 50[deg]C and decompose into urea and fluorinated olefin at higher temperatures. N,N′-diisopropylisoureas hydrochlorides act as efficient surfactants in aqueous solutions.
