Investigation of benzimidazole derivatives

The hydrochlorides of the corresponding 2-benzimidazolylmethylhydroxamoyl chlorides were synthesized by the chlorination of 1-methyl-2-formylbenzimidazole oxime and its 5-methyl and 5-nitro derivatives, and 2-benzimidazolylmethylnitrolic acids were obtained by nitration of the oximes. The products of these transformations react with acetylacetone and benzoylacetone in the presence of bases to give 1,5-substituted 3-[2-benzimidazolyl]-4-acyl-5-methylisoxazoles.See [1] for communication XXVII.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 6, pp. 812–815, June, 1972.     

Collision and rotation of solitons in three space-time dimensions

We investigate properties of soliton solutions in two space and one time dimension of two confining field theories, in particular rotation and Regge trajectories. Numerically we study the collision process in a two-soliton collision.     

Research on imidazo[1,2-a]benzimidazole derivatives XIII. Synthesis and properties of alcohols of the imidazo[1,2-a]benzimidazole series

Various hydroxy derivatives of imidazo[1,2-a]benzimidazole were synthesized from its 3-bromo, 3-formyl, and 3-acetyl derivatives. The properties and pharmacological activity of the products were studied.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 1, pp. 126–134, January, 1976.     

Transformations of 2-formyl-n-nitroarylimidazoles

Esters of-1-aryl--2-imidazolylacrylic acid were synthesized by the Wittig reaction from 2-formyl-1-arylimidazoles. The reaction of these aldehydes with arylamines and 1,2-dianilinoethane was examined.Considering the method used to prepare the esters, the trans structure can be assigned to them [9].Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 6, pp. 788–790, June, 1973.     

Laser action in some single and binary organic scintillator solutions

Experimental results are presented, which show that it is necessary to consider the absorption of pump radiation by electronically excited molecules for a proper interpretation of the operation of liquid organic lasers. The possibility of the use of binary organic scintillator solutions to obtain laser action in a rather broad spectral region is shown.
