Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Russian Journal of Physical Chemistry A called The influence of isomerism on the enthalpies of solution of dipyrrolylmethanes, Author is Berezin, M. B.; Guseva, G. B.; Semeikin, A. S.; V’yugin, A. I.; Smirnov, A. V., which mentions a compound: 2199-44-2, SMILESS is O=C(C1=C(C)C=C(C)N1)OCC, Molecular C9H13NO2, Electric Literature of C9H13NO2.
The enthalpies of solution of 3,3′,4,4′-tetramethyl-5,5′-dicarbethoxydipyrrolylmethane-2,2′ and its α,β- and β,β isomers in organic solvents of various natures were measured calorimetrically at 298.15 K. The enthalpies of transfer of the compounds from benzene into chloroform, pyridine, dimethylsulfoxide, and DMF were calculated Pyridine, DMSO, and formamide (proton acceptor solvents) specifically solvated the NH groups of dipyrrolylmethanes. Solvation interactions could be sterically complicated depending on the type of the isomer.
From this literature《The influence of isomerism on the enthalpies of solution of dipyrrolylmethanes》,we know some information about this compound(2199-44-2)Electric Literature of C9H13NO2, but this is not all information, there are many literatures related to this compound(2199-44-2).
