Abstract
The use of solid catalysts to promote organic reactions in water faces the inherent difficulty of the poor mass-transfer efficiency of organic substances in water, which is often responsible for insufficient reaction and low yields. To solve this problem, the solid surface can be manipulated to become amphiphilic. However, the introduction of surfactant-like moieties onto the surface of silica-based materials is not easy. By using an accessible dihydropyran derivative as a grafting linker, a surfactant-combined bifunctional silica-based solid catalyst that possessed an ionic liquid tail and a metal acetylacetonate moiety was prepared through a mild Lewis-acid-catalyzed ring-opening reaction with a thiol-functionalized silica. The surfactant-combined silica-supported metal acetylacetone catalysts displayed excellent catalytic activity in water for a range of reactions. The solid catalyst was also shown to be recyclable, and was reused several times without significant loss in activity.

Abstract
A copper-catalyzed cross-coupling reaction of epoxides with arylboronates is described. This reaction is not limited to aromatic epoxides, because aliphatic epoxides are also suitable substrates. In addition, N-sulfonyl aziridines can be successfully converted into the products. This reaction provides convenient access to β-phenethyl alcohols, which are valuable synthetic intermediates.

Abstract
Epoxides are versatile intermediates in organic synthesis, but have rarely been employed in cross-coupling reactions. We report that bipyridine-ligated nickel can mediate the addition of functionalized aryl halides, a vinyl halide, and a vinyl triflate to epoxides under reducing conditions. For terminal epoxides, the regioselectivity of the reaction depends upon the cocatalyst employed. Iodide cocatalysis results in opening at the less hindered position via an iodohydrin intermediate. Titanocene cocatalysis results in opening at the more hindered position, presumably via Ti(III)-mediated radical generation. 1,2-Disubstituted epoxides are opened under both conditions to form predominantly the trans product.

Abstract
Chronic exposure to allyl chloride (AC) is known to produce a central-peripheral distal axonopathy. To access the biomarker of exposure and elucidate the mechanism of neuropathy induced by AC, we performed a longitudinal observational study of malondialdehyde (MDA), anti-reactive oxygen species (anti-ROS), glutathione (GSH), catalase (CAT), glutathione peroxidase (GPx) and superoxide dismutase (SOD) in rats serum and sciatic nerve after 0, 3, 6, 9 and 12 weeks of AC administration. AC was administrated to Wistar rats by gavage at a single dosage of 200 mg/kg/per dose (three times per week). Rats were sacrificed after 0, 3, 6, 9 and 12 weeks of AC treatment, serum and sciatic nerves were quickly collected at 4 degrees C. The results showed that MDA levels in serum (115.4 and 126.2%) and sciatic nerve (130.5 and 145.3%) significantly increased (p<0.05) on 3rd week of AC treatment and at gait score of 2, and further changes of MDA levels were observed after 6, 9 and 12 weeks and at gait score of 3 and 4. While a decrease (p<0.05) in the activities of CAT on 6th week of AC intoxication and at gait score of 2 was observed in serum (81.2 and 72.8%) and sciatic nerve (71.7 and 70.7%). The other antioxidants also decreased in serum and sciatic nerve after 3, 6 and 9, 12 weeks' intoxication and at gait score of 2, 3 and 4. Significant (p<0.05) positive correlations were observed between serum and sciatic nerve in MDA levels (r=0.9162 and 0.9551, respectively) and CAT (r=0.9410 and 0.9557, respectively) activities as time went on and symptoms developed. Thus, AC intoxication was associated with elevation of lipid peroxidation and reduction of antioxidative status, and the time dependent changes of these indexes in Wistar rats' serum and sciatic nerve occurred. The misbalance of lipid peroxidation and antioxidation status might be one of mechanisms of toxic neuropathy induced by AC. MDA and CAT could be served as the biomarkers of AC exposure to afford the early diagnosis of AC-induced toxic neuropathy.
