The present study complements our previous studies of the reactions hydrogen atoms with C5 alkene species including 1- and 2-pentene branched isomers (2-methyl-1-butene, 2-methyl-2-butene, 3-methyl-1-butene), by studying C2–C4 alkenes (ethylene, propene, 2-butene, isobutene). aim current work is to develop a hierarchical set rate constants for Ḣ atom addition C2–C5 alkenes, both linear branched...

In the title hydrated molecular salt, C(6)H(7)ClN(+)·C(7)H(9)ClN(3) (+)·2Cl(-)·0.5H(2)O, the water O atom lies on a crystallographic twofold axis. In the crystal, inter-molecular N-H⋯Cl and O-H⋯Cl hydrogen bonds form layers perpendicular to the ac plane in which both the water mol-ecule and the chloride anion are involved in connecting the layers into a three-dimensional structure.

Rhodococcus sp. strain AD45 was isolated from an enrichment culture on isoprene (2-methyl-1,3-butadiene). Isoprene-grown cells of strain AD45 oxidized isoprene to 3,4-epoxy-3-methyl-1-butene, cis-1, 2-dichloroethene to cis-1,2-dichloroepoxyethane, and trans-1, 2-dichloroethene to trans-1,2-dichloroepoxyethane. Isoprene-grown cells also degraded cis-1,2-dichloroepoxyethane and trans-1, 2-dichlor...

synthesis of 4-(n,n- dimethylamino)-3-aryl-3-butene-2-one, ethyl-5-aryl-4-oxo-4h-pyran-2-carboxylate, ethyl-5-aryl-4-pyridones-2-carboxylate and 5-aryl-3-cyano-5-methyl-2-pyridones (aryl=3-thienyl, 2-furyl) are described.

Zeolite catalysts that could allow the efficient synthesis of n-butene, such as 1-butene, trans-2-butene, and cis-2-butene, in dimethyl ether (DME)-to-olefin (DTO) reaction were investigated using a fixed-bed flow reactor. The zeolites characterized by N2 adsorption desorption, X-ray diffraction (XRD), thermogravimetry (TG), NH3 temperature-programmed desorption (NH3-TPD). A screening ten avail...

2,4-Dichloro-, 4,6-dichloro-, 2,4,6-trichloroand tetrachloropyrimidine undergo nucleophilic displacements by 4-(dimethylamino)pyridine to give (pyrimidine-2,4-diyl)-1,1’-bis[4-(dimethylamino)pyridinium] dichloride, (pyrimidine-4,6-diyl)-1,1’-bis[4-(dimethylamino)-pyridinium] dichloride, (pyrimidine-2,4,6-triyl)-1,1’,1”-tris[4-(dimethylamino)pyridinium] trichloride, and (5chloropyrimidine-2,4,6-...
