Recently it has been suggested (1) that the properties of ɑ-metallocenyl carbonium ions can be best explained in terms of mesomeric ring effects not involving metal participation (2). The Ware and Traylor interpretation (1) suggests Ib as the major mesomeric form contributing to the resonance stabilization of the ion I, whereas the metal participation concept (2) envisages the contribution from Ic as the major stabilizing factor.
