β'-Chloro and β',γ'-unsaturated trichlorotitanium enolates, which were formed in situ by titanium(IV) chloride-mediated ring cleavage of 3,3-dialkylcyclobutanones and 3-[(trimethylsilyl)methyl]cyclobutanones, reacted with enones to give Michael adducts with keeping a labile β'-chloro or β',γ'-unsaturated group.

Comamonas testosteroni JH5 used 4-chlorophenol (4-CP) as its sole source of energy and carbon up to a concentration of 1.8 mM, accompanied by the stoichiometric release of chloride. The degradation of 4-CP mixed with the isomeric 2-CP by resting cells led to the accumulation of 3-chlorocatechol (3-CC), which inactivated the catechol 2,3-dioxygenase. As a result, further 4-CP breakdown was inhib...

Methanogenic oxidation of butyrate to acetate requires a tight cooperation between the syntrophically fermenting Syntrophomonas wolfei and the methanogen Methanospirillum hungatei, and a reversed electron transport system in S. wolfei was postulated to shift electrons from butyryl coenzyme A (butyryl-CoA) oxidation to the redox potential of NADH for H(2) generation. The metabolic activity of bu...

Some new 3-acetyl-5-(3-chloro-1-benzo[b]thiophen-2-yl)-2-substituted phenyl-2,3-dihydro-1,3,4-oxadiazoles and 2-(3-chloro-1-benzo[b]thiophen-2-yl)-5-substituted phenyl-1,3,4-oxadiazoles have been synthesized and evaluated for antimicrobial activity. Initially, 3-chloro-1-benzo[b]thiophene-2-carbonyl chloride (1) was prepared from cinnamic acid in the presence of chlorobenzene and thionyl chlori...

The compound 2-((1,3-dimethyl-1H-pyrazol-5-yl)(methyl)carbamoyl)benzene-diazonium hydrogen sulfate (10) was reacted with copper sulfate and sodium chloride, in the presence of ascorbic acid as reducing agent, to afford a mixture of the chlorinated epimers 4'-chloro-2,2',5'-trimethyl-2',4'-dihydrospiro[isoindoline-1,3'-pyrazol]-3-one (18) and (19), the epimers 4'-hydroxy-2,2',5'-trimethyl-2',4'-...

In the crystal structure of the title compound, [ZnCl(2)(C(5)H(4)ClN)(2)], discrete complex mol-ecules are found in which the Zn(II) cations are coordinated by two chloride anions and the N atoms of the two 3-chloro-pyridine ligands within a slightly distorted tetra-hedron. Moreover, inter-molecular C-Cl⋯Cl-C halogen inter-actions (Cl⋯Cl = 3.442 Å) are found between the building blocks.

Quinoline is a typical nitrogenous heterocyclic compound, which carcinogenic, teratogenic, and mutagenic to organisms, its wastewater difficult biodegrade directly. The bipolar electro-Fenton process was employed treat quinoline solution. process/reaction conditions were optimized through the single factor experiment. degradation kinetics of chemical oxygen demand (COD) analyzed. To get mechani...

The title compound, C(34)H(36)Cl(2)O(7), is a by-product from the reaction of 4-chloro-benzyl-zinc chloride with 3,4,5-trimeth-oxy-benzaldehyde. In each of the two 1,2-diphenyl-ethyl moieties, the two benzene rings are arranged in a trans conformation and make C(ar)-C-C-C(ar) torsion angles of 163.64 (19) and 174.43 (18)°. The crystal structure is stabilized by van der Waals inter-actions only.
