Pressure effects as mechanistic probes for homolytic thermal cobaltcarbon bond cleavage of cobalamins
Autor: H. J. Gamelkoorn, Sijbe Balt, M. W. G. De Bolster
Publikováno v: Recueil des Travaux Chimiques des Pays-Bas. 111:178-182
The effect of pressure on the rates of anaerobic thermal homolytic scission of the CoC bond in alkylcobalamins (RB12, R = adenosyl, methyl and neopentyl) has been determined in different solvents of varying viscosities. Homolytic fission is compared

The coordination chemistry of nonamethylimidodiphosphoramide: Part III. Compounds of nickel(II) iodide
Autor: M. W. G. De Bolster, W. L. Groeneveld
Publikováno v: Recueil des Travaux Chimiques des Pays-Bas. 91:643-649
Complex-formation between the ligand nonamethylimidodiphosphoramide (NIPA) and nickel(II) iodide has been investigated. By varying the solvent and the metal salt to ligand ratio, three compounds could be isolated, that were identified by chemical ana

Publikováno v: Recueil des Travaux Chimiques des Pays-Bas. 90:477-507
A number of new solvates and adducts containing hexamethylphosphoramide is reported. The solvates have the general formula M{[(CH3)2N]3PO}42+(anion)22−, in which M = Mg, Ca, Sr, Mn, Fe, Co, Ni, Zn and Cd and the anions are BF4−, ClO4− and B(C6H

A new model for coenzyme B12
Autor: R. J. van Delft, Sijbe Balt, M. W. G. De Bolster, Y. Van Den Winkel, H. de Koning, J. L. Van Der Baan, B. van Arkel, G. W. Klumpp
Publikováno v: Recueil des Travaux Chimiques des Pays-Bas. 107:23-24
A new cobaloxime-type model for coenzyme B12 has been synthesized. For this model strong steric repulsion between its dioxymethylene bridge and (one of) the axial ligands on cobalt presages enhanced rates of axial ligand exchange.

Publikováno v: Antimicrobial Agents and Chemotherapy. 21:881-886
Evidence was found that the inhibitory action of Cu(DMP)2NO3, the copper(I) complex of 2,9-dimethyl-1,10-phenanthroline (DMP), on Mycoplasma gallisepticum is a consequence of the ultimate toxicity of copper, and not that of the ligand, DMP. From upta
