Investigation of the molecular dynamics of some phenols and their acetyl isomers in solutions by NMR relaxation

STUDYING THE REACTION ROUTE OF Α, Β-Dibromo KETONE AT PRESENCES OF SOME AMINES

“…The acetophenones, their chalcone, α, β-dibromo ketone derivatives are impor tant compo unds in chemistry and are valuable synthetic building blocks in synthesis of various hete ro cyclic compounds . α, β-Dibromo ketones are useful synthons in the synthesis of a large number of pyrazolines, pyrazolines, isoxazoles etc [1][2][3][4][5][6][7][8][9][10][11] .…”

“…(2E)-2-bromo-1-(4-bromophenyl)-3-ethoxy-3-(thiophen-2-yl)prop-2-en-1-one (5). Yel low crystals, yield 87%, mp 165-168 ℃ (diastereomic mixture) .…”

Investigation of New Dihydropyridine Derivative Solutions by Using of 2d Dosy NMR

“…As well, NMR has important role at investigations of the formation of intermolecular complexes, association, self-organization, molecular recognition, reorientation and rearrangements of supramolecular structures under the action of various factors [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29]. Beside, NMR spectroscopy and its experimental equipment enable measurements of the self-diffusion coefficients (SDC) in the high-resolution mode, which in this case DOSY an important experimental method suitable for separation of the spectral contributions of different components of a system under study based on different sizes of the components.…”
