HON:C(CO2Et)2 (I) underwent reduction and condensation with certain β-diketones and a β-oxo aldehyde to give 2-pyrrolecarboxylic esters. Similarly, HON:C(CN)CO2Et (II) and certain β-diketones afforded 2-pyrrolecarbonitriles. The method has been applied to the synthesis of 5 previously known pyrroles. This synthetic approach constitutes the most direct route to 4 of these 5 pyrroles.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Ferrocene and Cobaltocene Derivatives for Non-Aqueous Redox Flow Batteries, published in 2015, which mentions a compound: 1273-73-0, mainly applied to redox flow battery ferrocene cobaltocene; substituent effect ferrocene cobaltocene redox flow battery; cycliability redox flow battery ferrocene cobaltocene; cobaltocene; electrolyte; ferrocene; redox flow battery; redox pair, Formula: C10BrFe.

Ferrocene and cobaltocene and their derivatives are studied as new redox materials for redox flow cells. Their high reaction rates and moderate solubility are attractive properties for their use as active materials. The cyclability experiments are carried out in a static cell; the results showed that these materials exhibit stable capacity retention and predictable discharge potentials, which agree with the potential values from the cyclic voltammograms. The diffusion coefficients of these materials are 2 to 7 times higher than those of other non-aqueous materials such as vanadium acetylacetonate, iron tris(2,2′-bipyridine) complexes, and an organic benzene derivative

The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: Bromoferrocene( cas:1273-73-0 ) is researched.Computed Properties of C10BrFe.Sato, Masaru; Motoyama, Izumi; Hata, Kazuo published the article 《Reactions of haloferrocenes. III. Reaction of haloferrocenes with copper(I) benzenethiolate, thiocyanate, acetate, and benzoate》 about this compound( cas:1273-73-0 ) in Bulletin of the Chemical Society of Japan. Keywords: haloferrocenes copper compound; copper compound haloferrocenes; ferrocenes halo copper compound; iodoferrocenes copper compound; iron organic compound. Let’s learn more about this compound (cas:1273-73-0).

Iodoferrocene reacted with copper(I) benzenethiolate in boiling pyridine to give ferrocenyl Ph sulfide in a quant. yield. The reaction of iodoferrocene with copper(I) thiocyanate gave diferrocenyl disulfide. The behavior of copper(I) acetate and benzoate toward haloferrocene was different from those of the other copper(I) salts: reactions in boiling pyridine gave the corresponding ferrocenyl ester, together with a small quantity of ferrocene, while the reaction in boiling toluene produced biferrocenyl as the main product. The reaction mechanism of the ferrocenyl ester and biferrocenyl formations was discussed.

Bertosa, Branimir; Kojic-Prodic, Biserka; Wade, Rebecca C.; Ramek, Michael; Piperaki, Stavroula; Tsantili-Kakoulidou, Anna; Tomic, Sanja published an article about the compound: 2-(7-Bromo-1H-indol-3-yl)acetic acid( cas:63352-97-6,SMILESS:O=C(O)CC1=CNC2=C1C=CC=C2Br ).Application of 63352-97-6. Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring.

The activity of a biol. compound is dependent both on specific binding to a target receptor and its ADME (Absorption, Distribution, Metabolism, Excretion) properties. A challenge to predict biol. activity is to consider both contributions simultaneously in deriving quant. models. We present a novel approach to derive QSAR models combining similarity anal. of mol. interaction fields (MIFs) with prediction of logP and/or logD. This new classification method is applied to a set of about 100 compounds related to the auxin plant hormone. The classification based on similarity of their interaction fields is more successful for the indole than the phenoxy compounds The classification of the phenoxy compounds is however improved by taking into account the influence of the logP and/or the logD values on biol. activity. With the new combined method, the majority (8 out of 10) of the previously misclassified derivatives of phenoxy acetic acid are classified in accord with their bioassays. The recently determined crystal structure of the auxin-binding protein 1 (ABP1) enabled validation of our approach. The results of docking a few auxin related compounds with different biol. activity to ABP1 correlate well with the classification based on similarity of MIFs only. Biol. activity is, however, better predicted by a combined similarity of MIFs + logP/logD approach.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Double-helical dinuclear bis(dipyrromethene) complexes Formed by self-assembly, published in 2000-11-17, which mentions a compound: 2199-44-2, mainly applied to transition metal dipyrromethene complex preparation; pyrromethene transition metal complex preparation; crystal structure transition metal dipyrromethene complex; helix double transition metal dipyrromethene complex preparation, Formula: C9H13NO2.

Bis(dipyrromethene) ligands linked by an alkyl spacer between β and β’ positions (I; n = 1, 2, 3) give helical dimers or monomers, dependent upon the length of the alkyl linker, upon complexation. Ligands consisting of methylene, ethylene, and propylene linkers -(CH2)n- (n = 1, 2, and 3) give helical dimers, while longer linking chains (n = 4, 5, or 6) give monomers or mixtures of dimers and monomers. X-ray crystal structures of the dimeric Zn complexes (n = 1, 2, and 3) reveal that the angles between dipyrromethene planes and the extent of helicity in the complexes differ as the length of the linker varies. The extent of helicity was assessed and is dependent upon the length and, specifically, the conformational preferences of the alkyl spacer unit. The presence of an ethylene linker gave complexes of greatest helicity. The use of a methylene spacer gave less helical structures upon complexation, while propylene spacers gave only slightly helical complexes. These studies identify the crucial importance that the conformational preferences of the β-β’ alkyl spacer group plays in the coordination algorithm of self-assembly to form dipyrromethene based complexes.
