e. Electrophilic aliphatic substitution reactions are chemical reactions in which an electrophile (an electron deficient species) removes a functional group in a compound. This back-side attack causes an inversion (study the previous slide): after the leaving group leaves, the other substituents shift to make room for the newly-bonded nucleophile, changing the stereochemistry of the molecule. Despite these reports, SciFinder search revealed five papers that reported the synthesis of (1H-indol-3-yl)methyl electrophile 6 (Table 1) 15,18,19,20,21.

(D) Electrophilic Substitution (Common in Aromatic compounds) : Electrophilic Substitution involves the attack by an electrophile. on relative stabilities of reactants and products. . In 1997, Catellani reported the first reaction for the construction of tri-substituted aromatics 4 by ortho alkylation/ipso Heck coupling termination of aryl iodides (Scheme 2) [1]. 1 The ready availability of the π-electrons makes benzene rings nucleophilic i. These reactions can be classified into the following five types. Mechanism of reactionThe electrophilic aliphatic substitution reaction.
