Abstract: A series of novel monocyclic cis-beta-lactams were prepared from phenoxyacetic acid as ketene source and imines derived from 1-chloro-3,4-dihydronaphthalene-2-carbaldehyde and respective amine using ethyl 4,5-dichloro-6-oxopyridazine-1(6H)-carboxylate (or 2-ethoxy carbonyl DCPN) as a carboxylic acid activator.This is the first time 2-ethoxy carbonyl DCPN has been used as an acid activator in synthesis of beta-lactams. The reaction was entirely diastereoselective leading to the formation cis-beta-lactam derivatives.These newly synthesized cis-beta-lactam were fully characterized by FT-IR, 1H NMR, 13C NMR, HRMS, CHNS and X-ray crystallography study. All this novel compound was also evaluated for their antibacterial and antifungal activities against certain strains of Gram-positive bacteria, Gram-negative bacteria and fungi. These compounds displayed moderate activity against using bacterial and fungal strains. Graphic abstract: [Figure not available: see fulltext.].

The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 66346-87-0, 6-Chloro-5-methylpyridazin-3-amine, introducing its new discovery.

A series of novel ([1,2,4]triazolo[1,5-b]pyridazin-6- yl)oxyalkylsulfonamides was synthesized and evaluated for the ability to inhibit platelet activating factor (PAF)-induced bronchoconstriction in guinea pigs. The compounds bearing a gem-dialkyl or a cycloalkylidene group at the 2 position of the sulfamoylpropyloxy group in the side chain and a methyl group at the 7 position were found to have potent activity. Among them, 2,2-diethyl-3-(7-methyl[l,2,4]-triazolo[1,5-b]pyridazin-6- yl)oxypropanesulfonamide (13) showed excellent anti-asthmatic activity. Compouds 13 may be of significant value in the treatment of asthma and other respiratory diseases. The structure-activity relationships in this series of compounds are discussed.

In heterogeneous catalysis, the catalyst is in a different phase from the reactants. Safety of 3,6-Dichloropyridazine, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 141-30-0, name is 3,6-Dichloropyridazine. In an article，Which mentioned a new discovery about 141-30-0

A series of alkyl (1-3), aryl (6), and benzo-annulated (4,5) heteroaromatic triphenylene analogues with B2N2C2 cores have been synthesized via chelation of pyridazine derivatives using difunctional Lewis acidic diborabiphenyl precursors. In contrast to triphenylene, NICS(1) calculations on 1 suggested high aromaticities for the central (-11.3 ppm) and outer borabenzene rings (-7.7 ppm), along with nonaromatic behavior for the pyridazine ring (-0.7 ppm). Crystal structure analyses supported this analysis. When the a- and c-faces of the pyridazine moiety were free of substitution (1, 3), planar structures resulted, but upon substitution, a twisted B 2N2C2 core was observed due to steric repulsion of neighboring hydrogen atoms (e.g., 5). The increase of steric bulk from H (1) to ?Pr (3) in the planar species was found to result in a dimeric, head-to-tail herringbone packing motif, held together by close intermolecular B…N interactions of 3.39 A. One-electron reduction by Cp*2Co was found to afford the radical anions of 3 and 5, which were characterized by broad, featureless singlets in the EPR spectra; [3] .-[Cp*2Co]- was characterized by X-ray crystallography. While the planar structures (1-4) were observed to possess weak fluorescence (PhiF = 0.02-0.08) with either yellow-orange (ca. 555 nm) or green emission (521 nm), the twisted structures (5, 6) were found to be nonfluorescent.
