How Many e Do We Want Donated? It depends on the specific case.For example, allyl-Mn(CO)s-Mn(CO)5 has 17 e,so we want 1 e donated ( → Mn: H H On the other hand,if we have... allyl-Mn(CO)4 we now need 3 e from the allyl radical Co H木/H co H co Mn' + co H-C Mn' co H CO XIV-10How Many e- Do We Want Donated? • It depends on the specific case.
