-
Paragraph 0028; 0040; 0044, (2018/05/16)
The invention relates to a synthesis method of a novel complex for drug testing, in particular to a Pb-containing complex Pb(bpbp)3(NO3)2, wherein bpbp represents 2,6-bis(2-(1-phenyl)benzimidazole)pyridine. The invention further relates to a crystal structure of the complex. The preparation method is simple and fast, and the complex is low in toxicity and high in yield. Compared with a conventional crystal culture method of the ligand complexes, the method has the advantages that solvents for synthesis are water and methanol, and a large quantity of crystals can be obtained in three days. Withadoption of a fluorescence analysis method, a fluorescence spectrum of interaction of a target product and BSA (bovine serum albumin) is tested; the fluorescence quenching phenomenon of BSA indicatesthat the complex has stronger interaction with BSA, so that the complex can be applied to biological drug detection.
Synthesis of Ruthenium Complex Based on 2,6-Bis(1-(phenyl)-1H-benzo[d]imidazol-2-yl)pyridine and 2-(1-Phenyl-1H-benzo[d]imidazol-2-yl)benzoate and Catalytical Oxidation Property of 1-(1H-Benzo[d]imidazol-2-yl)ethanol to 1-(1H-Benzo[d]imidazol-2-yl)ethanone with H2O2

A new ruthenium complex, Ru(bpbp)(pbb)Cl, based on 2,6-bis(1-(phenyl)-1H-benzo[d]imidazol-2-yl)pyridine (bpbp) and 2-(1-phenyl-1H-benzo[d]imidazol-2-yl)benzoate (pbb) was synthesized. The complex Ru(bpbp)(pbb)Cl could catalytically oxidize 1-(1H-benzo[d]imidazol-2-yl)ethanol to 1-(1H-benzo[d]imidazol-2-yl)ethanone with H2O2 as oxidant. Influence of temperature and catalyst amount on the oxidation reaction was evaluated. The reaction optimal conditions are as follows: molar ratio of catalyst to substrate to H2O2 is 1: 1000: 3000, the proper reaction temperature is 50°C and reaction time lasts 5 h, and the isolated yield of 1-(1H-benzo[d]imidazol-2-yl)ethanol to 1-(1H-benzo[d]imidazol-2-yl)ethanone under the optimal reaction conditions is 57%.

A convenient and selective oxidation of alcohols with hydrogen peroxide to give aldehydes and ketones has been developed. Using in situ generated iron chloride complexes [Fe(L3)2Cln] [n=0-1, L3 =6-(N-phenylbenzimidazoyl)-2-pyridinecarboxylic acid], aldehydes and ketones were obtained in good yield and excellent selectivity after a short reaction time at room temperature.
