A superacid-promoted method for the synthesis of 9,9-diarylfluorenes is described. The chemistry involves cyclizations and arylations with biphenyl-substituted heterocyclic ketones and a mechanism is proposed involving superelectrophilic intermediates. The key reactive intermediates-dicationic and trication fluorenyl cations have been observed by low-temperature NMR and the mechanism has been further studied using DFT calculations.

The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 141-30-0, 3,6-Dichloropyridazine, introducing its new discovery.

Discovery of a highly selective, potent, and safe non-carboxylic acid, non-hydantoin inhibitor of aldose reductase (AR) capable of potently blocking the excess glucose flux through the polyol pathway that prevails under diabetic conditions has been a long-standing challenge. In response, we did high-throughput screening of our internal libraries of compounds and identified 6-phenylsulfonylpyridazin-2H-3-one, 8, which showed modest inhibition of AR, both in vitro and in vivo. Initial structure-activity relationships concentrated on phenyl substituents and led to 6-(2,4-dichlorophenylsulfonyl)-2/f-pyridazin- 3-one, 81, which was more potent than 8, both in vitro and in vivo. Incorporation of extant literature findings with other aldose reductase inhibitors, including zopolrestat, resulted in the title inhibitor, 19m, which is one of the most potent and highly selective non-carboxylic acid, non-hydantoin inhibitors of AR yet described (IC50, 1 nM; ED 90 vs sciatic nerve sorbitol and fructose, respectively, 0.8 and 4.0 mg/kg). In rats, its oral bioavailability is 98% and it has a favorable plasma t1/2 (26 ± 3 h).

A series of N--2-butylimidazoles containing variously substituted diazine or pyridine moieties either as their free bases or N-oxide derivatives attached to the 4-position of the imidazole ring was synthesized and tested for interaction with the AT1 receptors of the rat adrenal cortex membranes (receptor binding assay).Some compounds were then chosen for further evaluation in vivo in the A II-induced pressor response in conscious normotensive rats.The most potent in the AT1 binding assay were found to be compounds in which the diazine or pyridine ring nitrogen is adjacent to the point of attachment between the two heteroaromatic rings such as 2-butyl-4-(3,6-dimethylpyrazin-2-yl)-1-<<2'-(1H-tetrazol-5-yl)biphenyl-4-yl>methyl>-1H-imidazole (3b) or 2-butyl-4-<5-(methoxycarbonyl)pyrid-2-yl>-1-<<2'-(1H-tetrazol-5-yl)biphenyl-4-yl>methyl>-1H-imidazole (6c).The binding affinities and oral activities of the pyridine N-oxide imidazoles in which a stabilizing group ortho to the pyridine ring nitrogen is present were markedly improved as in 2-butyl-4-<(3-methoxycarbonyl)-6-methyl-N-oxopyridin-2-yl>-1-<<2'-(1H-tetrazol-5-yl)biphenyl-4-yl>methyl>-1H-imidazole 31b.Molecular modeling studies were carried out to determine the molecular electrostatic potential values of related model systems and to correlate their receptor interaction energies with the observed activities of our compounds.

Reference of 14959-32-1, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.14959-32-1, Name is 3-Chloro-6-(methylamino)pyridazine, molecular formula is C5H6ClN3. In a Article，once mentioned of 14959-32-1

BACKGROUND: Optimization studies on compounds initially designed to be herbicides led to the discovery of a series of [6-(3-pyridyl)pyridazin-3-yl]amides exhibiting aphicidal properties. Systematic modifications of the amide moiety as well as the pyridine and pyridazine rings were carried out to determine if these changes could improve insecticidal potency. RESULTS: Structure?activity relationship (SAR) studies showed that changes to the pyridine and pyridazine rings generally resulted in a significant loss of insecticidal potency against green peach aphids [Myzus persicae (Sulzer)] and cotton aphids [(Aphis gossypii (Glover)]. However, replacement of the amide moiety with hydrazines, hydrazones, or hydrazides appeared to be tolerated, with small aliphatic substituents being especially potent. CONCLUSIONS: A series of aphicidal [6-(3-pyridyl)pyridazin-3-yl]amides were discovered as a result of random screening of compounds that were intially investigated as herbicides. Follow-up studies of the structure-activity relationship of these [6-(3-pyridyl)pyridazin-3-yl]amides showed that biosteric replacement of the amide moiety was widely tolerated suggesting that further opportunities for exploitation may exist for this new area of insecticidal chemistry. Insecticidal efficacy from the original hit, compound 1, to the efficacy of compound 14 produced greater than 10-fold potency improvement against Aphis gossypii and greater than 14-fold potency improvement against Myzus persicae.
