Conclusions
-
1.
Study has been made of the interaction of chromium and iron vapors with toluene, mesitylene, and durol on liquid-nitrogen cooled surfaces. IR spectroscopy has been used to confirm the low-temperature formation of previously unknown bisarene iron (0) complexes. Decomposition temperatures have been determined for these compounds.
-
2.
The fact that the skeletal vibration frequencies of the various bisarene chromium complexes were essentially identical suggests that the strength of the metal-ligand bond increases as more and more methyl substituents are introduced into the benzene ring.
