Four perfluorohexyl carbinols have been prepared from the corresponding Grignard reagent and benzaldehyde, terephthalaldehyde, isophthalaldehyde, and trimesaldehyde. The corresponding secondary alcohols were then transformed by alkylation and acylation reactions to form a total of 14 ethers (methyl, ethyl, propyl, and n-hexyl ethers) and esters (acetyl and 2-ethylhexanoyl), respectively. Furthermore, 11 perfluoroalkyl carboxylates were prepared from aromatic, heteroaromatic, and aliphatic mono-, di-, tri-, and tetracarboxylic acids and tridecafluorooctanol. The wettability of all 29 materials was investigated by the water contact angle measurements of thin films on glass surfaces. In up to six cases, contact angles greater than 130° were observed, which indicates that the products might be suitable candidates for the impregnation of surfaces. With their relatively short perfluoroalkyl side-chains and therefore low bioaccumulativity, the target compounds might be beneficial alternatives to established products.

A combination of dimethylzinc, perfluoroalkyl iodide, and LiCl afforded a new type of perfluoroalkyl (RF) zinc ate complex. These complexes show much greater thermal stability than conventional perfluorinated metal species, such as RF-lithium species and Grignard reagents, and they can be used at room temperature or higher. The results of DFT calculations on the origin of the enhanced stability are reported and the synthetic utility of RF-zincate complexes is demonstrated.

Paradigm shift from alkaline (earth) metals to early transition metals in fluoroorganometal chemistry: Perfluoroalkyl titanocene(III) reagents prepared via not titanocene(II) but titanocene(III) species

Perfluoroalkyl (RF) titanocene reagents [Cp2Ti IIIRF] synthesized via [Cp2TiIIICl] rather than [Cp2TiII] show new types of perfluoroalkylation reactions. The [Cp2TiIIIRF] reagents exhibit a wide variety of reactivity with carbonyl compounds including esters and nitriles, and selectivities far higher than those reported for conventional RFLi and RFMgX reagents.
