Mori, Nobuo; Asano, Yuzuru; Tsuzuki, Yojiro published the artcile< Intramolecular hydrogen bonds. XIV. Correlation of the hydroxyl and the carbonyl frequencies of methyl salicylates with Hammett substituent constants>, SDS of cas: 22717-55-1, the main research area is salicylates Hammett constant; Hammett constant salicylates.
The ir OH and C(O) stretching spectra of methyl 4- or 5-substituted salicylates were measured in dilute CCl4, and the resp. peak-frequencies correlated with ordinary Hammett σ-constant The best linear relation was established between the γOH and the (σOH-0.38 σCO2Me) values and between the γC(O) and the (σCO2Me-0.49σOH) values, where σOH and σCO2Me are the σ-constant of a substituent with respect to the OH and the CO2Me group, resp. Besides, in other internally bonded phenol systems, including o-bromophenols, 2,6-dihalophenols, and salicylic acids, the plotting of the OH frequencies against the (σOH-Aσx) values gave the best linear relation, where A is a constant depending on the kind of proton acceptor, X. The value of A can be a measure of the electronic effects of the substituent, influencing the bonded OH frequency through X.
Bulletin of the Chemical Society of Japan published new progress about Hydrogen bond. 22717-55-1 belongs to class chlorides-buliding-blocks, and the molecular formula is C8H7ClO3, SDS of cas: 22717-55-1.
