| Abstract: | 1/1 complex formation between benzene-d6 and Cr(CO)3(η6-arene)] (arene = C6H5R (R = H, Me, OMe, Cl), C10H8) has been observed by PMR spectroscopy. The equilibrium constant in the case of arene =C6H6 confirms earlier chemical evidence that the Cr(CO)3] unit exerts an electron-with-drawing effect upon aromatic rings which is approximately equal to that of the nitro group. |
