In the two-dimensional title coordination polymer, [Ni(C(8)H(3)BrO(4))(C(14)H(14)N(4))(H(2)O)](n), the Ni(II) atom adopts a distorted octa-hedral geometry, being ligated by three O atoms from two different 5-bromo-benzene-1,3-dicarboxyl-ate ligands, two N atoms from two 1,2-bis-(imidazol-1-ylmeth-yl)benzene ligands and one coordinated water mol-ecule. The Ni atoms are bridged by the 5-bromo-ben...
The Sn(IV) atom in the centrosymmetric anion of the title salt, (C4H7N2)2[Sn2(C4H9)2(C2O4)Cl6], is coordinated in a distorted octa-hedral mode by two O atoms of a bridging oxalate moiety, three Cl atoms and a C atom of an n-butyl group. The latter is disordered over two sets of sites in a 0.66:0.33 occupancy ratio. N-H⋯O and N-H⋯Cl hydrogen bonds involving the 2-methyl-imidazolium cation and ne...
In the title compound, C(14)H(15)N(5)O(4), the central -C=N-N-C(=O)-C- bridge is nearly planar [maximum deviation = 0.037 (1) Å] and forms dihedral angles of 7.37 (9) and 73.33 (5)°, respectively, with the benzene and imidazole rings. The dihedral angle between the benzene and imidazole rings is 66.08 (9)°. The meth-oxy and nitro groups are nearly coplanar with the benzene and imidazole rings, ...
3-methyl-1-(4-sulfobuthyl)-1-H-imidazol-3ium hydrogen sulfate, as a dual acidic ionic liquid (DAIL), was found to be an efficient catalyst for the simple, rapid and green synthesis of substituted trisphenols from the condensation of different substituted phenols and 2,6-bis (methylol) phenols (BMP). DAIL catalyst efficiently promoted the reaction between phenols and BMPs with a variety of funct...
The biheterocyclic derivative of the phosphonic glycine analogue is prepared selectively by reaction between α-azidoamino diethyl methylphosphonate and 1-(prop-2-yn-1-yl)-1H-benzo[d]imidazole. dipolar -1,3 cycloaddition using Click Chemistry was carried out in a solvent water/ethanol mixture ratio 1:1. Copper sulphate pentahydrate sodium ascorbate are used catalytic amounts. compound [diethyl [...
V-RAF murine sarcoma viral oncogene homolog B1 (BRAF) is a serine/threonine-specific protein kinase that is mutated with high frequency in cutaneous melanoma, and many other cancers. Inhibition of mutant BRAF is an attractive therapeutic approach for the treatment of melanoma. A triarylimidazole BRAF inhibitor bearing a phenylpyrazole group (dimethyl-[2-(4-{5-[4-(1H-pyrazol-3-yl)-phenyl]-4-pyri...
Monomeric copper(I) alkyl complexes that possess the N-heterocyclic carbene (NHC) ligands IPr, SIPr, and IMes [IPr = 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene, SIPr = 1,3-bis(2,6-diisopropylphenyl)imidazolin-2-ylidene, IMes = 1,3-bis(2,4,6-trimethylphenyl)imidazol-2-ylidene] react with amines or alcohols to release alkane and form the corresponding monomeric copper(I) amido, alkoxide, or...
