Nucleophilic Aromatic Substitution (NAS) - Master …
WebThe electrophilic aromatic substitution (EAS) is a chemical reaction in which an atom attached to an aromatic system is replaced by an electrophile. Within the category of EAS reactions, there are a number of important chemical reactions which are named after their discoverers. Despite being discovered many years ago, these named reactions ... In nucleophilic aromatic substitution (NAS), all the trends you learned in electrophilic aromatic substitution operate, but in reverse. The first trend to understand is that electron withdrawing groups (EWG’s) dramatically increasethe rate of reaction, not decrease it. From this, it follows that the more … See more Let’s review electrophilic aromatic substitution (EAS). What have we learned? 1. The aromatic ring acts as a nucleophile, and attacks an added electrophileE 2. An … See more In fact, a substitution reaction does occur! (But, as you may suspect, this isn’t an electrophilic aromatic substitution reaction.) In this substitution reactionthe C-Cl bond breaks, … See more Unlike in electrophilic aromatic substitution, there are no “ortho-,para-” or “meta-” directors. The position of substitution is controlled by the placement of the leaving group. … See more One of the most eye-opening aspects of nucleophilic aromatic substitution is noting that fluorine is often used as a leaving group. This is seen in Sanger’s reagent for sequencing peptides, to take one example (more on that below). … See more todd\u0027s wallet
