Reactive Troponoids ando-Aminophenol. III. The Reaction of 2-Bromo-7-methoxytropone

{Tris[2-(5-bromo-2-oxidobenzyl­idene­amino)eth­yl]amine}manganese(III)

In the title complex, [Mn(C(27)H(24)Br(3)N(4)O(3))], the Mn(III) ion is six-coordinated in a distorted octa-hedral environment by three N atoms and three O atoms from the trianion of the hexa-dentate ligand tris-[2-(5-bromo-2-oxidobenzyl-idene-amino)eth-yl]amine. All three N (and O) atoms are cis to each other. The three N and the three O atoms are in a fac conformation among each other.

Adsorption Isotherms 2-aminophenol and 4-aminophenol on Carbon Nonotube

Present research paper deals with the adsorption isotherms rate 2-amino phenol and 4-amino phenol on multi-wall carbon nanotube which performed by changing the amount of solution concentration in ppm unit. According to difference between two under studied substances are in substitution of NH2 in ortho and para position , more adsorption of 4-aminophenol on carbon nanotube demonstrate that para ...

7-Bromo-1-(3-fluoro­phenyl­sulfon­yl)-2-methyl­naphtho­[2,1-b]furan

In the title compound, C(19)H(12)BrFO(3)S, the 3-fluoro-phenyl ring makes a dihedral angle of 80.85 (5)° with the mean plane [r.m.s. deviation = 0.009 (2)Å] of the naphtho-furan fragment. In the crystal, mol-ecules are linked by slipped π-π inter-actions between the furan and the outer benzene rings of neighbouring mol-ecules [centroid-centroid distance = 3.756 (3) Å and slippage of 1.189 (3) Å].

7-Bromo-1-(4-chloro­phenyl­sulfan­yl)-2-phenyl­naphtho[2,1-b]furan

In the title compound, C(24)H(14)BrClOS, the S-bound 4-chloro-phenyl ring is nearly perpendicular to the plane of the naphthofuran fragment [dihedral angle = 83.34 (3)°] and the phenyl ring in the 2-position is rotated out of the naphthofuran plane by a dihedral angle of 15.23 (5)°. The crystal structure is stabilized by aromatic π-π inter-actions between the furan and the central benzene rings...
