Farnier, M.; Drakenberg, T. published the artcile< Nuclear magnetic resonance conformational studies of C-substituted formylpyrroles II. Barrier to internal rotation in 5-substituted 2-formylpyrroles>, HPLC of Formula: 7126-50-3, the main research area is formylpyrrole potential barrier rotation; pyrrole formyl rotation barrier; conformation formylpyrrole NMR temperature.
The effect of temperature on the NMR spectra of Et 5-formylpyrrole-2-carboxylate and 2,5-diformylpyrrole allowed determination of the activation parameters for rotation of the CHO group by line-shape anal. of the CHO signals. Introduction of the EtO2C or CHO at C-5 caused a decrease in the barrier to rotation as expected from their electron-withdrawing properties.
Journal of the Chemical Society, Perkin Transactions 2: Physical Organic Chemistry (1972-1999) published new progress about Molecular rotation. 7126-50-3 belongs to class esters-buliding-blocks, and the molecular formula is C8H9NO3, HPLC of Formula: 7126-50-3.
