IN THE TITLE XANTHONE DERIVATIVE [SYSTEMATIC NAME: 9-hy-droxy-5,10-dimeth-oxy-2,2-dimethyl-11-(3-methyl-but-2-en-1-yl)-2,3,4,12-tetra-hydro-1,7-dioxatetra-phen-12-one], C(25)H(28)O(6), the xanthone ring system is roughly planar, with an r.m.s. deviation of 0.1038 (1) Å. The chromane ring is in a half-chair conformation and the 3-methyl-but-2-enyl substituent is axially attached with an (+)-anti...
The bacterial strains IMB-1(T) and CC495(T), which are capable of growth on methyl chloride (CH(3)Cl, chloromethane) and methyl bromide (CH(3)Br, bromomethane), were isolated from agricultural soil in California fumigated with CH(3)Br, and woodland soil in Northern Ireland, respectively. Two pesticide-/herbicide-degrading bacteria, strains ER2 and C147, were isolated from agricultural soil in C...
a new carbazole- containing polymer has been synthesized for further photophysical studies. efficient synthesis of the substituted methyl methacrylate has been accomplished via microwave assisted synthesis of 1 - chloro - 4-carboxy -5,6, 7, 8- tetrahydrocarbazole followed by further steps, such as reduction of the 4-substituted methyl carboxylate, dechlorination of the ring and at last, the rea...
[1] Methyl chloride concentrations were measured in the upper 200 m of the water column of the NW Atlantic during three cruises along the same track in spring, summer and fall of 2003. Distinct seasonality was apparent, with the surface waters being either undersaturated or close to equilibrium with the atmosphere in spring, but with supersaturation of the warmer waters in summer and fall. Cool...
THE TITLE COMPOUND [SYSTEMATIC NAME: N-methyl-3-(1-naphth-yloxy)-3-(2-thien-yl)propan-1-aminium chloride], C(18)H(20)NOS(+)·Cl(-), was crystallized from 1,4-dioxane. Twofold rotational disorder exhibited by the thio-phene ring in a 0.580 (5):0.420 (5) ratio represents two different conformations of the mol-ecule that exist in the same crystal form. The crystal structure contains strong N-H⋯Cl h...
