Write the condensed structural formula and the formula of 3-pentanol. Write condensed structural formula, such as CH3CH3, and describe the molecular geometry at each carbon atom. - propene - 1-butanol - ethyl propyl ether Write possible structural or condensed formulas (isomers) for the following...
Recrystallization of the complexes [Bi(S2CNEt2)X2], X = Cl, Br, or I, from dimethylformamide–n-butanol results in the formation of [Bi5(S2CNEt2)8X7]·.dmf (dmf = dimethylformamide). The three complexes are isomorphous and have been characterized structurally by single-crystal X-ray diffr...
To satisfy the γ-Al2O3 stoichiometry, deviating from the chemical formula of a spinel, M3O4 (M=a metal or mixed metals), the Al atomic positions are not fully occupied. Vacancies distribute over both the tetrahedral and octahedral sites 8a and 16d (spinel sites); however, the work of ...
(2R,3S)-1,4- bis(3-bromobenzoyloxy)-3-(2-nitroimidazol-1-yl)methoxy-2-butanol of formula I. For example, the objective compound is obtained by the following steps; protecting the hydroxy group to be left intact of a nucleoside analogue of formula II with a methoxymethyl group or the...
Since the discovery of its photocatalytic properties, titanium dioxide has remained one of the most popular and widely used metal oxide photocatalysts. Its major drawback, however, lies in the narrow region (UV) of sunlight necessary to produce reactive oxygen species. This have been countered by...
Studies on utilization of hemicelluloses from cereal straws and SCB have demonstrated to be a potential fermentation feedstock in production of ethanol, acetone, butanol, and xylitol. The current uses of xylan on an industrial scale involve their conversion to xylose, xylitol and furfural. Xylitol ...
13.The reinforcing agent according to claim 12, wherein the support is made of a plastic coated with a metal. 14.The composition according to claim 1, wherein the silane-functional polymer has an end group represented by formula (V):wherein R3represents a linear or branched, monovalent hydr...
An isostructural pseudopolymorph of 9-deoxo-9a-aza-9a-methyl-9a-homoerythromycin A is new and has the monoclinic space group, average unit cell parameters as given in the specification. An isostructural pseudopolymorph of 9-deoxo-9a-aza-9a-methyl-9a-homoerythromycin A of formula (I) is new...
(2R,3S)-1,4-dipivaloyloxy-3-[(2-nitroimidazol-1-yl)methoxy]-2-butanol. It is recommended that this new compound where M is H atom is obtained, for example, by preparing a compound of formula II using 1,2,3,4-butanetetraol as raw material followed by pivaloylation of only the ...
Complexes 1, 2 and 4 have an elongated square-pyramidal geometry with an unusually long bond from the penta-coordinated Cu(II) centres to the oxygen atoms of the apically coordinated solvent (methanol, ethanol or n-butanol) molecules for the terminal Cu(II) ions, and a square planar ...
