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 UV absorption spectra were measured in anhydrous ethanol, and their wavelengths of absorption maximum, λmax, were recorded. Also, 234 λmax values of 1-substituted phenyl-2-arylethylene compounds (XAEY, where X is substituted phenyl) were collected. The excited-state substituent constants of three pyridyl groups and 23 substituted Ph groups (a total of 26) were obtained by means of the 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 (data not shown)) as another data set, quant. correlation analyses were performed by employing the obtained excited-state substituent constants as a parameter, and good results were obtained for the two data sets. The reliability of the obtained excited-state substituent constant values was verified. The results of this paper provided excited-state substituent constants for the studied compounds and application of optical properties of conjugated organic compounds containing aryl groups. In addition to this study using 3-Chlorobenzylchloride, there are many other studies that have used 3-Chlorobenzylchloride(cas: 620-20-2Category: chlorides-buliding-blocks) was used in this study.
3-Chlorobenzylchloride(cas: 620-20-2) has been used in the reaction of 3-methoxybenzyl chloride and ethyl 4-bromobenzoate in pure water, using zinc dust and a Pd catalyst.Category: chlorides-buliding-blocks
