摘要：

The 13C NMR spectra of diferocenylcyclopropenone (1) and the triferrocenylcyclopropenium (2) and ferrocenyldiphenylcyclopropenium (3) cations in non-acidic media are analyzed with special reference to the information they afford concerning charge distribution in these species. A delocalization of the positive charge into the remote unsubstituted five-membered rings of 2 and 3 is indicated. The role of the metal as a conduit for this effect is suggested. © 1979.
