Reaction options, alkoxide vs hydroxide vs amine addition to the key intermediate (o-nitrosoimine) generated in the Davis–Beirut reaction of an o-nitrobenzylamine substrate, are reported to explain the nucleophilic addition selectivity of this one-pot indazole-forming process. The hydroxide addition/deprotection pathway as well as the fate of the resulting o-nitrosobenzaldehyde were both uncovered
Synthesis and characterization of some new Cd(II) and Zn(II) macrocyclic Schiff base complexes derived from cyclocondensation of three new linear aromatic (N4) amines and 2,6-diacetylpyridine. Crystal structure and biological activity studies
case of cadmiumcomplex by 1H and 13C NMR spectroscopy. The crystalstructure of [CdL1(CH3OH)](ClO4)2 has been determined. In this complex, the Cd(II) ion is coordinated to five nitrogen donor atoms of the ligand and one oxygen atom from methanol in a N5O environment. The geometry around the cadmium can be better described as in a slightly distorted pentagonal-pyramidal. The synthesized compounds have

2‐((2‐(2‐aminobenzylamino)ethylamino)methyl)benzenamine (L1), 2‐((3‐(2‐aminobenzylamino)propylamino)methyl)benzenamine (L2), and 2‐((4‐(2‐aminobenzylamino)butylamino)methyl)benzenamine (L3) were synthesized and then their reaction with 2‐hydroxybenzaldehyde, 2‐nitrobenzaldehyde, and 2‐hydroxy‐3‐methoxybenzaldehyde were investigated. Treatment of L1, L2, and L3 with the former aldehydes gave derivatives of quinazolines
