The latter were used to prepare two light-fluorous N,N'-dialkyl-imidazole-2-ylidene diiodo palladium(II) complexes. The fluorous partition coefficients of the light-fluorous olefins, iodides, and triflates were measured in perfluoro(methylcyclohexane)/toluene biphasic system, which revealed that the shorter and environmentally friendlier perfluoroalkyl chains of the light-fluorous ponytails results in lower fluorous partition coefficients, especially as the number of methylene groups increases.

AB - Levulinic acid (LA) is one of the most studied platform chemicals produced from a wide range of carbohydrates containing biomass including agricultural residues and food wastes. The reduction of the carbonyl group of LA leads to the transient formation of 4-hydroxyvaleric acid (4-HVA), which readily undergoes facile dehydration to give gamma-valerolactone (GVL) in very high yields. The homogeneous catalytic conversion of LA to GVL via 4-HVA can be achieved by transition metal complexes by using molecular hydrogen. Alternatively, the transfer hydrogenation of LA with formic acid or sodium formate or isopropanol can be used for the transformation of LA to GVL. Although no catalytic systems have been reported to yield 4-HVA selectively, the formation of chiral GVL by the asymmetric reduction of LA confirms its transient formation. The application of transition metal complexes as catalysts for the hydrogenation and transfer-hydrogenation of LA are reviewed including the use of chiral ligands for the asymmetric catalytic reductions of LA.

While maintaining the superhydrophobicity of the membrane, we have addressed the problem of bioaccumulation by immobilizing perfluoro-tert-butyl groups on the commercially-available aerogels. The resulting fluorous aerogels were electrosprayed on the top of commercial PVDF membranes to fabricate superhydrophobic membranes. The effects of varying the alkyl chain between the aerogel and the perfluoro-tert-butoxy groups and the concentration of the modified aerogel were studied to identify the optimal membrane for membrane distillation (MD). The fabricated membranes were tested for MD performance with sodium dodecyl sulfate (SDS) and saline water (3.5% NaCl). The F-1-SiG100 membrane (prepared by grafting 300 mg of 1-(nonafluoro-tert-butoxy)-4-butylethoxysilane aerogel on 300 mg of PVDF-HFP) exhibited superhydrophobicity (water contact angle = 151.2 degrees), a very rough surface (R-a = 2.17 mu m), and an extremely low surface free energy (0.82 +/- 0.17 mN m(-1)). It also showed high resistance to low surface energy feed of up to 0.5 mM SDS and saline water.
