Abrupt room temperature switching (T(c) = 295 K with a 5 K hysteresis) was achieved in a neutral Fe(II) complex based on a 2-(1H-pyrazol-1-yl)-6-(1H-tetrazol-5-yl)pyridine ligand. Structural characterization and spin crossover study (via SQUID magnetometry, photoexcitation and X-ray absorption spectroscopy) in the solid state are described.
The title compound, 4-amino-5-benzoyl-1-benzyl-2-(4,5,6,7-tetrahydro-1H-indol-2-yl)- 1H-pyrrole-3-carbonitrile, was synthesized for the first time in a 40% yield by reaction of N-benzyl-3-imino-5,6,7,8-tetrahydro-3H-pyrrolo[1,2-a]indol-1-amine and 1-chloroacetophenone K2CO3/MeCN system (reflux, 6 h). product characterized 1H-NMR, 13C-NMR, IR spectroscopy, elemental analysis.
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...
Two potentially tripodal ligands, tris(1-phenyl-1H-1,2,3-triazol-4-yl)phosphine oxide (OP(1,2,3Tz1?Ph)3) and tris(1-benzyl-1H-1,2,3-triazol-4-yl)phosphine (OP(1,2,3Tz1?benz)3), were used in reactions with [Re(CO)5Br] (NEt4)2[Tc(CO)3Cl3]. While the formation of rhenium complexes bidentate tridentate coordinated phosphine oxides was observed, for technetium only cationic OP(1,2,3Tz1?R) ligands is...
An electron-transport-type host was synthesized using a benzo[4,5]furo[3,2-d]pyrimidine (BFP) core to develop high triplet energy host. The designed have both the tetraphenylsilyl blocking group and hole-transport-type carbazole group. In device application, used as an mixed with 3,3†-di(9H-carbazol-9-yl)-1,1†-biphenyl (mCBP) in blue phosphorescent organic light-emitting diodes (PhO-LEDs) doped...
A series of novel compounds, namely 1-(diethoxyphosphoryl)-3-(4-ones-1H-1,2,3-triazol-1-yl)propan-2-yl carboxylic esters, were designed on the basis of the diazafulvene intermediate of imidazole glycerol phosphate dehydratase (IGPD) and high-activity inhibitors of IGPD, and synthesized as inhibitors targeting IGPD in plants. Their structures were confirmed by 1H-NMR, 13C-NMR, 31P-NMR and HR-MS....
In the title compound, C(15)H(13)N(5), the N-containing heterocycles are linked by an ethyl-ene spacer in a gauche conformation, the N-C-C-C torsion angle along the linker being 60.1 (3)°. The dihedral angle between the terminal benzotriazole and benzimidazole rings is 39.02 (6)°. In the crystal, adjacent mol-ecules are connected by N-H⋯N hydrogen bonds, forming an infinite chain along the c ax...
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...
A novel binary compounds as 3-(1,3-diphenyl-1H-pyrazol-4-yl)-2-phenyl-2H-benzo[f]indazole-4,9-dione (10) and fused 2-hydroxy-3-(4-hydroxy-7-methoxy-2-oxo-1,2-dihydroquinolin-3-yl)naphthalene-1,4-dione (7) naphtho[2,3-b]furan-3,4,9(2H)-trione (6) based on lawsone ‘that plays important precursor’ was synthesized by reaction with 1,3-diphenyl-1H-pyrazole-4-carbaldehyde halo-compounds, such 2-chlor...
