Study of synthesis of 2-(2-alkoxyphenyl)-1H-imidazoles. Comparison of oxidative aromatization reactions of imidazolines [PDF]

open access: yes, 2006
The reaction of methyl salicylate with ethane-1,2-diamine has been used to prepare 2-(2-hydroxyphenyl)-1H-imidazoline. This compound was alkylated with alkyl halides to give five new 2-(2-alkoxyphenyl)-1H-imidazolines (alkyl = propyl, isopropyl, isobutyl,

Kinetics and mechanism of organocatalytic aza-Michael additions: direct observation of enamine intermediates. [PDF]

open access: yes, 2012
The imidazoles 1a–g add to the CC-double bond of the iminium ion 2 with rate constants as predicted by the equation log k = sN(N + E). Unfavourable proton shifts from the imidazolium unit to the enamine fragment in the adduct 3 account for the failure of

2-[(1H-Imidazol-2-yl)disulfanyl]-1H-imidazole [PDF]

open access: yesActa Crystallographica Section E Structure Reports Online, 2011
In the title molecule, C(6)H(6)N(4)S(2), a twofold rotation axis passes through the mid-point of the S-S bond. The C-S-S-C torsion angle is 83.62 (17)°. π-π stacking between imidazole rings of adjacent mol-ecules is observed in the crystal structure, the centroid-centroid distance being 3.447 (2) Å. Inter-molecular N-H⋯S hydrogen bonding results in the
