The insect repellents N,N-diethyl-3-methylbenzamide (Deet) and the racemate and 1S,2'S stereoisomer of 2-methylpiperidinyl-3-cyclohexene-1-carboxamide (AI3-37220) were tested against Anopheles albimanus Wiedemann and Aedes aegypti (L.) in laboratory human-volunteer assays. Estimated skin doses of Deet or racemic AI3-37220 required to reduce biting by 95% in Ae. aegypti were 2.3 and 3.5 x 10(-2)...

The partial hydrogenation of benzene to cyclohexene is an economically interesting and technically challenging reaction. Over the last four decades, a lot of work has been dedicated to the development of an exploitable process and several approaches have been investigated. However, environmental constraints often represent a limit to their industrial application, making further research in this...

Selective and rapid reductLon of nitro compounds is still area of considerable synthetic interestl, particularly when a molecule has several other reducible moieties. Numerous new reagents*-l4 have been developed for reduction of aromatic nitro compounds, however little attention has been paid to the reduction of aliphatic nitro compound&ry,S, which are traditionally reduced by high pressure ca...

The secondary organic aerosol (SOA) yields from the laboratory chamber ozonolysis of a series of cycloalkenes and related compounds are reported. The aim of this work is to investigate the effect of the structure of the hydrocarbon parent molecule on SOA formation for a homologous set of compounds. Aspects of the compound structures that are varied include the number of carbon atoms present in ...

Hydrogen evolution coupled with the photochemical oxygenation of cyclohexene with water was observed in the system sensitized by Sn(IV)-porphyrin adsorbed on Pt loaded TiO2 nano-particles in aqueous acetonitrile solution upon visible light irradiation.

The heats of adsorption on magnesium oxide of six linear chain alkanes (C4 to C 9 ) , of the corresponding 1-mono-olefins and of the cycl ic compounds cyclohexane, cyclohexene, 1.4-cyclohexadiene and benzene have been determined by gas-solid chromatography and extrapolated to zero surface coverage. The values obtained with n-alkanes are linearly dependent on the carbon atom number. By compariso...

Framework Ti-substituted, 3-D hexagonal mesoporous, Ti-SBA-12, obtained for the first time by direct hydrothermal synthesis, oxidises bulky molecules such as cyclohexene and cyclooctene to the epoxides with >96% selectivity at high conversion levels (>60%).

A series of heterodinuclear catalysts, coordinated by a Schiff base ligand, for ring opening copolymerisation phthalic anhydride/cyclohexene oxide, highlight the best metal combinations fast and selective catalysis.

A novel cyclohexene compound (1), which is structurally related to theobroxide (2), was isolated from a culture filtrate of the fungus, Lasiodiplodia theobromae IFO 31059. The potato micro-tuber-inducing activity of this compound was observed at a concentration of 10(-3) M in the medium, whereas theobroxide (2) showed its activity at 10(-5) M.
