Reaction Scheme (starting materials, reagents, product; this is NOT a curved arrow MECHANISM) -> Predict the final structure of your synthesized direct and disperse azo dye. This is an ELECTROPHILIC AROMATIC SUBSTITUTION REACTION. Step 1: THE AMINE TO BE DIAZOTIZED: Convert to amine to a diazonium salt. Amine to be diazotized: aniline-2-sulfonic acid SO3H NH2 Step 2: THE AMINE TO BE COUPLED: Based on ortho/para directing groups, identify the most likely site for electrophilic aromatic substitution. Compound to be coupled: 2-naphthol-6,8-disulfonic acid (dipotassium salt) K* Step 3: FORM DIAZO FUNCTIONAL GROUP R-N=N=R: Connect the amine to be diazotized, at the site most likely for electrophilic aromatic substitution on the amine to be coupled. In the process, the diazonium salt is converted from [R-N=N]+ to R-N=N-R.

NOC XT Ph CH₂ Both primary and secondary amines add to a ß-unsaturated aldehydes and ketones to yield ß-amino aldehydes and ketones rather than the alternative imines. Under typical reaction conditions, both direct and conjugate modes of addition occur rapidly. But because the reactions are reversible, they generally proceed with thermodynamic control rather than kinetic control so the more stable conjugate addition product is often obtained to the complete exclusion of the less stable direct addition product. Draw curved arrows to show the movement of electrons in this step of the mechanism. Arrow-pushing Instructions H H CH3NH₂ CH3 H-A :A Ph NHCH3 вон CH3 :A H-A 8b
