Page/Page column 8, (2009/05/29)
A dendron (2) comprising a focal point (4) and a plurality of fluorinated end groups (9) is disclosed, including one having a thiol, a silane, a carboxylic acid, a phosphonate or another moiety at the focal point suitable for chemisorption to a substrate

(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.

The first examples of liquid crystalline chloro-bridged dinuclear palladium organyls carrying semiperfluorinated alkyl chains at their peripheries have been synthesised. The liquid crystalline properties were investigated using polarised optical microscop

Either Markovnikov or anti-Markovnikov regioselectivity can be achieved at will during the hydroboration-oxidation of perfluoroalkyl(aryl)ethylenes by varying the hydroborating agent.
Convenient synthesis of thiols and disulfides in the polyfluorinated series incorporating a butylic spacer
Mureau, Natacha,Guittard, Frédéric,Géribaldi, Serge
, p. 2885 - 2889 (2007/10/03)
New fluorinated thiols R(F)(CH2)(p)SH and disulfides [R(F)(CH2)(p)S]2 containing a butylic spacer (p=4) between the perfluorinated part and the thiol (or disulfide) function were easily obtained in good yields with a purity higher than 98%. This allows us to obtain homologues (p>4) for their use as synthetic intermediates or as constituents for molecular organized systems. (C) 2000 Elsevier Science Ltd.

The simple and effective syntheses of acids and alcohols of general formula CnF2n+1(CH2)mY (Y=CO2H, CH2OH; n=6,8 and m=4,5) have been described.
Copper-catalyzed addition of perfluoroalkyl iodides to unsaturated alcohols and transformation of the addition products

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.
