A new fluorinated anionic surfactant Cl(CF2) 6O(CF2)2SO3N(C2H 5)4 was prepared and characterized. The application of the fluorosurfactant allowed the fluoroalkylation to occur in the water without adding organic solvent. The addition of perfluoroalkyl iodides with olefins and alkynes under the initiation of Na2S2O4 in water in the presence of the fluorosurfactant gave the corresponding adducts in good to excellent yields. The fluorosurfactant was suitable for a radical addition process. A new surfactant Cl(CF2)6O(CF 2)2SO3N(C2H5) 4 was prepared and its properties were measured. The fluorinated surfactant was applied to the fluoroalkylation of perfluoroalkyl iodides with olefins and alkynes. The reactions gave the corresponding adducts in water and avoided the use of organic solvent. The aqueous solution with the surfactant proved to be an effective medium for a radical process.

(Chemical Equation Presented) The rational design, synthesis, and characterization of a series of novel perfluorinated dendrons 14a,b, 25a,b, 26a,b, and 18 are described. The dendrimers were designed to have a thiol at the focal point for attachment to a gold surface to enable the fabrication of self-assembled monolayers (SAMs). Perfluorinated tails were attached to the periphery to provide solubility in supercritical carbon dioxide, and to increase the hydrophobicity and the stability of self-assembled monolayers formed. Mitsunobu reactions were utilized to provide high-yielding steps allowing large-scale production of the novel dendrimers.

(FORMULA PRESENTED) Five-to seven-membered lactones were prepared from ω-hydroxyalkyl iodides and CO by atom transfer carbonylation without the need for transition metal catalysts. The reaction proceeds via a hybrid radical/ionic mechanism in which the intramolecular alcoholysis of an ω-hydroxyacyl iodide, arising from atom transfer carbonylation, leads to the lactone.

Perfluoroalkyl iodides, in the presence of a catalytic amount of Ti0 generated in situ, add to alkenes in dimethoxyethane solvent to afford 1-(n-perfluoroalkyl)-2-iodoalkanes in moderate to good yields. 1-Alkenes, 1-alkynes and alkenes containi

Iodoperfluoroalkyl alcohols RFCH2CHI(CR2)nOH (RF = C6F13; R = H, CH3; n = 1-3, 9) have been readily prepared in high yield by the addition of perfluoroalkyl iodides RFI to allylic and other unsaturated alcohols at 120 deg C in the presence of a catalytic amount (10percent mol) of metallic copper powder.The dibenzoyl peroxide-induced reaction gave lower yields of the addition products in most cases.The chemical changes of iodoperfluoroalkylated alcohols to epoxides and alcohols are described.A discussion of the by-products obtained and of the reaction mechanism is provided.
