WebJul 19, 2011 · First, the –CH 3 on a methyl ketone is converted to a trihalomethyl group. This decent leaving group allows the carbonyl to undergo a nucleophilic acyl substitution reaction with the NaOH already present in the reaction. This is called the haloform reaction. Iodine can be used instead of bromine. Web1. For two nucleophiles with the same nucleophilic atom, the stronger base is the stronger nucleophile 2. A negatively charged nucleophile is always stronger than its conjugate acid 3.

The prototypical super leaving group is triflate, and the term has come to mean any leaving group of comparable ability. Compounds where loss of a super leaving group can generate a stable carbocation are usually highly reactive and unstable. Thus, the most commonly encountered organic triflates are methyl triflate and alkenyl or aryl triflates, all of which cannot form stable carbocation…
