Abstract
A series of substituted bis(fluorobenzene)chromium complexes, (C6H4FX)2Cr, where X is H, F, Cl, CH3, or CF3, have been synthesized by cocondensing Cr atoms and fluoroarenes. The 19F chemical shifts of these compounds correlate well with those of the corresponding C6F5X system suggesting that the overall electron-withdrawing effect of a π-bonded Cr on each ring is similar to the effect of four ring fluorine substituents.Keywords
