β¦ Synopsis
As we haVe previously pointed out], the position of the Transition State along the reaction coordinate is a matter of controversy among workers in the field of nucleophilic addition reactions to carbonyl compounds. Some authors claim that the transition state is always "Reactant-like" whatever may be the nucleophile ; others think, on the contrary, that the structure of the transition state depends upon the nucleophile and can be either "Reactant-like", or "Product-like" or somewhere in between.
