Abstract

Furthermore, it would be reasonable to expect kz'/(k-1'+ kz') to be considerably smaller for I- than for the other two nucleophiles, because kz'should be effectively independent of Nu-, while k-1'would probably be much larger for I-than for either Br-or SCN-, since I-is in all probability a considerably better leaving group than the other two anions. Thus, even though kl'for I-attacking 2 was larger than kl'for SCN-by about the same amount as in the attack of ...
