WebApr 1, 2005 · A green electrophilic aromatic substitution reaction (EAS), nitration of tyrosine, has been developed for use in the undergraduate laboratory. This reaction allows students to consider the varied aspects of EAS including activating and deactivating groups and o, p, m directors in a green environment. WebThis is often called a +R (for resonance) effect, and this activates the ring towards EAS. Other groups contain an electronegative atom attached via a π-bond (e.g., C=O) that makes the group electron-withdrawing. These groups act as π-acceptors, drawing electron density away from the ring via resonance. tisbury pfister swivel shower
