A new insight into the push-pull effect of substituents via the stilbene-like model compounds

In this paper, authors report on 1-pyridyl-2-arylethenes, 1-furyl-2-arylethylenes, 1,2-diphenylpropylenes and substituted cinnamyl anilines as stilbene-like model compounds to investigate the factors dominating the push-pull effect of substituents via usi

Determination and application of the excited-state substituent constants of pyridyl and substituted phenyl groups

Thirty six 1-pyridyl-2-arylethenes XCH=CHArY (abbreviated XAEY) were synthesized, in which, X is 2-pyridyl, 3-pyridyl and 4-pyridyl and Y is OMe, Me, H, Br, Cl, F, CF3, and CN. Their ultraviolet absorption spectra were measured in anhydrous ethanol, and their wavelengths of absorption maximum λmax were recorded. Also, the 234 λmax values of 1-substituted phenyl-2-arylethylene compounds (XAEY, where X is substituted phenyl) were collected. The excited-state substituent constants (Formula presented.) of three pyridyl groups and 23 substituted phenyl groups (total of 26) were obtained by means of curve-fitting method. Taking the λmax values of 358 samples of bi-arylethene derivatives as a data set and 126 samples of bi-aryl Schiff bases (including nine compounds synthesized by this work) as another data set, quantitative correlation analyses were performed by employing the obtained (Formula presented.) as a parameter, and good results were obtained for the two data sets. The reliability of the obtained (Formula presented.) values was verified. The results of this paper can provide excited-state substituent constants for the study and application of optical properties of conjugated organic compounds containing aryl groups.

Ligand-free palladium-catalysed oxidative Heck reaction of 4-vinylpyridine with arylboronic acids: Selective synthesis of (E)-4-styrylpyridines

A ligand-free palladium-catalysed oxidative Heck reaction of various arylboronic acids with 4-vinylpyridine has been developed, achieving (E)-4-styrylpyridines with high selectively in moderate to good yields. A plausible mechanism for the formation of (E)-4-styrylpyridines has been proposed.

A [2+2] cross-photodimerisation of photostable olefins via a three-component cocrystal solid solution

A ditopic hydrogen-bond-donor template in the form of resorcinol facilitates a [2+2] cross-photodimerisation of 4-Cl-stilbazole and 4-Me-stilbazole in a rare cocrystal solid solution. A photoreaction does not proceed with the olefins individually or as a solid solution composed solely of the two olefins.

Electronic Interactions in Aromatic Compounds. Direct Electronic Interaction between Aromatic Rings in Conjugated and Non-Conjugated cis-Compounds

A study of charge transfer equilibria between a series of cis- and trans-4-styrylpyridines and cis- and trans-1-(4-X-phenyl)-2-(4-pyridyl)cyclopropanes with iodine has been carried out in CCl4.Acidity constants for these heteroaromatic compounds were determined.The results obtained for the two types of measurements show that through-space conjugation, due to overlap of the non-parallel ?-orbitals of the two aromatic systems, operated in both cis-systems.
