Regio- and stereoselectivity in preparation of benzene bridged bis- and tris-Troeger's bases
Valik, Martin,Dolensky, Bohumil,Petrickova, Hana,Kral, Vladimir
, p. 609 - 621 (2007/10/03)
Synthetic strategy for novel multiple Troeger's base derivatives is presented. Compounds were prepared in three steps: o-nitrobenzoylation of benzene-1,2- and -1,3-diamines 3 followed by reduction of nitro and amide groups to amino functions and treatment
Mass spectrometer as a probe in the synthesis of 2-substituted benzimidazoles
Ramana, Devalla V.,Kantharaj, Ethirajulu
, p. 2485 - 2496 (2007/10/02)
The pyrolysis of N,N'-diacyl-1,2-benzenediamines leads to the formation of 2-substituted benzimidazoles. This new synthetic approach towards the synthesis of 2-substituted benzimidazoles is developed based on the electron impact studies of N,N'-diacyl-1,2-benzenediamines under 70 eV conditions, in which important fragment ions corresponding to 2-substituted benzimidazoles are observed. The mechanisms and ion-structures, proposed in the mass spectral study, are supported by high-resolution, B/E and B2/E linked-scan spectra and Collision Activated Decomposition (CAD)-B/E linked-scan spectra.
Metal Template Reactions. XVI. Design and Synthesis of Primary Diamine Ligands with Additional Nitrogen Donor Atoms
Black, David St. C.,Rothnie, Neil E.
, p. 1141 - 1147 (2007/10/02)
Five new primary diamines (8), (10), (12), (20) and (22) have been synthesized.These compounds contain additional nitrogen donor atoms suitable for metal chelation.An improved preparation of the triamine (6) is also reported.
