摘要
The 13C NMR spectra of π-arenechromium complexes XC6H5Cr(CO)2L (where I, L CO; II, L PPh3; X aliphatic and aromatic substituents) were investigated. The effect of the nature of the substituent X on the chemical shifts of the carbon atoms of the aromatic ring in these complexes was analyzed. It was established that a correlation exists between δ(13C) and σR (Taft's constant) in complexes I, not only for C(4) nuclei but also for C(3) metal atoms, the difference being that the slopes of the corresponding curves are opposite. © 1979.
