Intramolecular methyl migration in dinuclear rhodium complexes
Abstract
trans-[(C5Me5Rh)2(µ-CH2)2Me2] reacts with acid and L (MeCN, pyridine, etc.) to give cis- plus trans-[(C5Me5RhL)(µ-CH2)2(MeRhC5Me5)][PF6] which, at higher temperatures, equilibrate by a process which involves the methyl moving from one metal to the other.
