Herein, we have reported the facile synthesis of various benzimidazole / benzothiazole by using DBU-Iodine-Iodide as a green and simple catalyst. The R2NH+I3 complexes been formed reacting an aqueous mixture ammonium iodide molecular iodine with solution amine. structure has confirmed spectroscopic techniques. prepared amine-iodine screened catalyst in benzothiazoles. Among DBUH+I3complex found...

In the title complex, [CdI(2)(C(16)H(12)N(2)O(2))(2)], the Cd(II) atom is located on a twofold rotation axis and is four-coordinated by two N atoms from symmetry-related 2-(2-fur-yl)-1-(2-furyl-meth-yl)-1H-benzimidazole ligands and two I atoms in a distorted tetra-hedral configuration. The benzimidazole rings in adjacent mol-ecules are parallel, with an average inter-planar distance of 3.486 Å....

Biofouling is the undesirable growth of organisms on artificial and natural structures immersed in either seawater or freshwater. It causes huge economic loss and also the global prohibition on known antifouling agents has led to increase hunt for safe and effective antifouling agents. In the past, marine natural products have shown tremendous potential by providing new skeletons which could be...

retinoids with a tetrahydronaphthalene structure (Fig. 1), was synthesized using an NaHSO3 addition product of 5,6,7,8tetrahydro-5,5,8,8-tetramethyl-2-naphthalene-carboxaldehyde (compound I) as a starting material, which was prepared as described.1 The condensation of compound I and 4-ethylamino3-amino-ethylbenzoate (mp: 73 ̊C) in DMF for 70 h gave the title compound (recrystallized from hexane/...

The title compound, [Cd(NO(3))(2)(C(11)H(13)N(3))(2)], was synthesized by hydro-thermal reaction of Cd(NO(3))(2) and S-2-(pyrrolidin-2-yl)-1H-1,3-benzimidazole. The Cd atom lies on an inversion centre. The distorted octa-hedral Cd environment contains two planar trans-related N,N-chelating S-2-(pyrrolidin-2-yl)-1H-1,3-benzimidazole ligands in one plane and two monodentate nitrate ligands. N-H⋯O...

The title compound, C(17)H(15)N(2)O(2) (+)·Cl(-)·H(2)O, was synthesized from benzimidazole and furfryl chloride in dimethyl-formamide. The cationic benzimidazolium ring is connected to two furan rings via methyl-ene bridges. The furan rings make dihedral angle of 79.09 (18)° with respect to each other, and make dihedral angles of 73.92 (12) and 72.58 (13)° with respect to the benzimidazole ring...

Crystals of the title compound, 2C(26)H(18)N(4)O(2)·C(7)H(8), were obtained from the reaction of 8-hydroxy-quinoline with 1,2-phenyl-enediamine in methanol and recrystallized from toluene. The compound contains three essentially planar ring systems: the benzimidazole ring (r.m.s. deviation = 0.039 Å) and two 8-hydroxy-quinoline rings (r.m.s. deviations of 0.0056 Å in both rings). The benzimidaz...

In the title complex, [Mn(C(9)H(4)N(2)O(4))(H(2)O)(2)](n), the Mn(II) atom is in a distorted octa-hedral coordination completed by one N atom from one 1H-benzimidazole-5,6-dicarboxyl-ate ligand, two O atoms from two different 1H-benzimidazole-5,6-dicarboxyl-ate ligands, and three O atoms from three water mol-ecules. Two bridging water mol-ecules and two bridging carboxyl-ate groups from a 1H-be...

Mono- and binuclear arene–ruthenium(II) complexes with imidazole-containing ligands were prepared by the reaction of (L1 = bis(imidazole-1-yl)methane; ImH 1H-Imidazole; BImH 1H-Benzimidazole) [(p-cym)Ru(µ-Cl)2]2 dimers. When bis(imidazole-1-yl)methane reacted in methanol, a complex type [Ru2(L1)2(p-cym)2Cl2]Cl2 (2) cyclic structure was synthesized, whereas using acetonitrile as solvent under sa...
