| Description
| - Two series of chromium(0)-(aryl)aminocarbene complexes substituted on the ligand phenyl ring were prepared and electrochemically investigated: pentacarbonyl((N,N-dimetylamino)(phenyl)carbene(chromium(0) (Ia-e) and chelated tetracarbonyl((.eta.2-N-allyl-N-allylamino)(phenyl)carbene(chromium(0) (IIa,c-e). For comparison, a tungsten analogue of IIc (III) and a chromium chelate bearing a methyl substituent instead of the phenyl group IV were taken into the study. The intramolecular interactions of p-substituents of the ligand phenyl ring with the reduction and oxidation centres of the molecule of complex (followed electrochemically using LFER enabled to localize the corresponding electron transfer. The influence of the type of coordination, the substituent on the ligand phenyl ring and the central metal atom on oxidation and reduction potentials is discussed.

- Byly připraveny a elektrochemicky charakterizovány dvě serie (aryl)aminokarbenových komplexů chromu substituovaných na ligandovém fenylovém kruhu : pentakarbonyl[(N,N-dimethylamino)(fenyl)karben]chromu (Ia - e) a chelatovaný tetrakarbonyl[(.eta.2-N-allyl-N-allylamino)(fenyl)karben]chromu (IIa,c,d,e) . Pro srovnání byly přiřazeny další dva komplexy: wolframový analog látky IIc (III) a chromový chelát IV nesoucí namísto fenylu methylový substituent. Intramolekulární interakce p-substituentů na ligandovém fenylovém kruhu s redukčním, resp. oxidačním centrem v molekule komplexu (které byly sledovány elektrochemicky za použití LFER[1]) umožnily lokalizovat příslušné přenosy elektronů. Byl přitom diskutován vliv typu koordinace, vliv substituentů na fenylu a vliv centrálního atomu na oxidační a redukční potenciál. (cs)
