On the basis of spectrophotometric measurements, constants have been determined for adduct formation between bis-macrocyclic
complexes of copper(II) and aliphatic diamines. For these systems, the influence of reactant structure on the specific features
of complexation has been established.

1. | Stability constants for alkali metal complexes of composition [ML]+ and a copper complex [CuLCl]+, which are formed via treatment of alkali metal 2,4-dinitrophenolate or copper chloride with a series of carbamoyl phosphine oxide derivatives, have been determined in anhydrous solutions. |
2. | The most stable complexes are formed by ligands containing an aryl substituent attached to the phosphorus atom. |

1-Chloroalkyl isocyanates and 1-chloroalkylcarbodiimides undergo regioselective cyclization with nitriles and esters of 2-benzimidazolylacetic acid to give derivatives of 1-oxo and 1-arylimino-1,2,3,5-tetrahydrobenzo[4,5]imidazo[1,2-c]pyrimidine respectively. The cyclocondensation of 1,1-dichloroalkyl isocyanates or N-(1-chloroalkylidene)carbamates with nitriles and esters of 2-benzimidazolylacetic acid afforded 1,5-dihydrobenzo[4,5]imidazo[1,2-c]pyrimidin-1-one derivatives.Translated from Zhurnal Organicheskoi Khimii, Vol. 40, No. 11, 2004, pp. 1715–1724.Original Russian Text Copyright © 2004 by Vovk, Lebed, Pirozhenko, Tsymbal.For communication III see [1]. 相似文献

Phosphoalkenes (1), (R, RI, and RII = H, Hal, Nalk2) show alternative nucleophilic properties towards HX acids or transition metal salts, and depending upon reagent characteristics form addition products throught one of P=C double bond atoms. Coordination of a ligand to a cation by its π-electron donor is also observed due to quazidegeneration of higher occupied molecular orbital. 相似文献

Results of investigation of Cd and Zn surface resistance in magnetic field are given. This field is normal to the metal surface and parallel to hexagonal crystal axis. Oscillations observed in these conditions are discussed and possibly explained by propagation of light damping electromagnetic wave. 相似文献
