Imine-tetrahydroquinazoline tautomerism in a tosilated Schiff base
(MDPI, 2010)Condensation of the selectively tosilated N-(2-aminobenzyl)-4-methylbenzenesulfonamide with 2-hydroxybenzaldehyde gives rise to (E)-N-(2-(2- hydroxybenzylideneamino)benzyl)-4-methylbenzenesulfonamide in the solid state, ... -
Synthesis of dicompartimental schiff base ligands : Crystal structure of (n-n'-bis(3- methoxy or 3-ethoxysalicylidene)-1,2-diamine-2-methylpropane
(MDPI, 2010)The condensation of 3-methoxy or 3-ethoxy-2-hydroxybenzaldehyde and 1,2 diamine -2-methylpropane, to yield at the dianionic hexadentate Schiff base ligands H2 Ln (H2 L1 , H2 L2 respectively). The ligands have been characterised ... -
Double imidazolidine condensation in a polynucleating Schiff base
(MDPI, 2010)Condensation of pentaethylenehexamine and 3-bromo-5-chlorosalicylaldehyde yielded the bisimidazolidine Schiff base ligand 5,6\'-(1E,1\'E)-(2,2\'-(3,3\'-(ethane-1,2- diyl)bis(2-(3-bromo-5-chloro-2-hydroxyphenyl)imidazolid ... -
Crystal structure of (n-n'-bis(3-ethoxysalicylidene)-1,2-diaminopropane
(MDPI, 2009)Three hexadentate Schiff base ligands were obtained by condensation of 3-ethoxy-2-hydroxybenzaldehyde and different diamines (1,2-diaminoethane, 1,2-diaminopropane, 1,2-diamino-2-metylpropane) to yield H2Ln (H2L1, H2L2 and ... -
The crystal structure of a compartmental heptadentate ligand
(MDPI, 2009)2-(2-hydroxyphenyl)-1,3-bis[4-(2-hydroxyphenyl)-3-azabut-3-enyl]-1,3-imidazolidine (H3L) was obtained with high purity by Schiff's condensation between 5-bromosalicyaldehyde and triethylenetetramine. Its recrystallisation ...
