Conformational interchange in acyclic hydrazines

Nuclear magnetic resonance spectrometry

“…46, NO. 5, APRIL 1974 • and cyclic tetraalkylhydrazines (1229,1230), .ZV-alkylpiperidine and morpholine N-oxides (1231), N,N'-dialkylhexahydropyrimidines (1232) and N-aminobicyclo-[2.2.1]hept-5-ene-2,3-endo-dicarboximide (1233) have been reported. The conformations of l-anilinonaphthalene-8sulfonate have been studied (1234) by fluorescence and PMR spectrometry.…”

Study of solvents effect on distribution of configurational and conformational isomers of apo-tirucallol theoretically and experimentally

“…The dynamic investigations of conformations have achieved great progress by using NMR or HPLC method [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21]. During the last decades, Lunazzi, Mazzanti, Casarini and coworkers have reported a series of conformational studies with some interesting discoveries [5][6][7][8][9].…”

“…Static conformational analyses of acylated tetrahydrobenzazepines have been performed [12]. Conformational studies of other compounds, such as the bioactive cyclic heptapeptide from marine origin [13], acyclic hydrazines [14], etc. have been done [15][16][17][18][19][20].…”

Lithiumamide, -hydrazonide und -ketazide als Bausteine acyclischer, cyclischer und spirocyclischer Bor-, Phosphor- und Siliciumverbindungen sowie monomerer und dimerer Amino-imino-borene

“…Das erste Bis(silyl)hydrazin entstand in der Reaktion des Me 3 SiCl mit Hydrazin als Isomerengemisch, (Me 3 Si) 2 N-NH 2 und Me 3 SiNH-NHSiMe 3 [34,35,36,37,38,39] . Hiermit konnten erstmals Silylgruppenwanderungen nachgewiesen werden [35,36,37,40,41,42,43,44] .…”
