Intermolecular contacts in the crystal structures of specifically varied halogen and protonic group substituted azines

A series of azines featuring differently halogen and protic group substituted pyridine, pyrimidine and pyridazine compounds have been synthesized and studied in terms of their crystal structures in order to develop a better understanding of the links between structural conditions and molecular packing behavior. Complemented by the structure results of related compounds known from the literature, intermolecular contact relationships connected to the present substance types were found, having potential use in future crystal engineering of similar compounds. This primarily involves the formation of N?I contacts aside from specific halogen?halogen and hydrogen bond type interactions.

Pyridyl Dicyanoquinodimethane Acceptors for Electroactive Solids

A new synthetic strategy for dicyanoquinodimethane electron acceptors is presented and used to synthesize six such compounds for the first time.The general sequence is substitution of alpha,alpha’-dicyanoxylene alpha anions with electophiles followed by oxidative dehydrogenation.Unlike most previous examples, these quinodimethanes (QDs) are alpha substituted, rather than ring substituted; thus, the substituents increase the aspect ratio of the QDs and extend the ? systems.All contain at least one pyridyl substituent at an alpha position, and the set includes polar, cationic, and phosphonic acid derivatives.The particular compounds were chosen for incorporation into specific types of potentially electroactive solids, although, in principle, the syntheses could accomodate a wide variety of other functional groups.The neutral QD compounds display two reversible reductions, while the cations show single, partially reversible electrochemical transitions.Syn-anti isomerism was noted for several of the QDs, and proton NMR assignments obtained by 2D COSY methods are reported.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 141-30-0 is helpful to your research. Reference of 141-30-0

On the metalation of 3-substituted and 3,6-disubstituted pyridazines

Metalation, pyradazines, lithiation Starting from 3,6-dichloropyridazine, a series of new pyridazines bearing lithiation-directing groups in alpha-position to a ring nitrogen atom (compounds 1-5) was prepared. Metalation employing lithium alkylamides was found to afford ortho-substituted pyridazines. The regioselectivity, depending on the nature of the metalating agent, is discussed.

Thermodynamic study on the gas chromatographic separation of the enantiomers of aromatic alcohols using heptakis(2,3-di-O-methyl-6-O-tert- butyldimethylsilyl)-beta-cyclodextrin as a stationary phase

Gas chromatographic separation of the enantiomers of nineteen structurally related aromatic alcohols was investigated as a function of temperature using a heptakis(2,3-di-O-methyl-6-O-tert-butyldimethylsilyl)-beta-cyclodextrin- coated capillary column. Thermodynamic parameters were determined and compared with those obtained with the nonchiral, reference stationary phase, OV-1701. While the -DeltaH and -DeltaS values for the more retained enantiomers of all nineteen alcohols are comparable on the chiral stationary phase used, the -Delta(DeltaH) and -Delta(DeltaS) values are considerably different. Of all the solutes tested, enantiodiscrimination was the greatest for the 2,6-difluoro-alpha-methylbenzyl alcohol.
