Electrophilic Aromatic Substitution Objective The objective of this experiment was to illustrate electrophilic aromatic substitution by synthesizing p-nitroanilide (as well as ortho) from acetanilide by nitration. The para form was separated from the ortho form based on solubility properties using recrystallization techniques. Synthetic equations: Physical Properties & Hazards of Reagents/Products: (all taken from Sigma-Aldrich website) Acetanilide MM = 135.16 g/mol Melting point =

Literature Survey 2. Literature Survey Literature survey indicated 135 possible routes for the synthesis of 2-Aminobiphenyl. It must be noted that all routes available were lab-scale and no patents for the desired compound were available. Also‚ majority of these synthesis routes gave extremely low yields of our desired product and produced a number of other by-products in higher yields. Therefore‚ only the pathways giving significant yields of the desired product have been listed below. i. Suzuki

with metallic oxides. These composites which are conducting polymers have been widely used because of their lower density as well their good environmental stability as in the case of polyaniline (PAN). In the present work ‚ in situ polymerization of aniline was carried out in the presence of Fe3O4 nano particles to synthesize polyaniline/Poly(p-hydroxyaniline)/ Fe3O4 (PAN/PHAN/ Fe3O4) composites. The composites‚thus synthesized have been characterized by Fourier transfer infrared(FTIR) spectrophotometer

nitrogen atom instead of the carbon of the chain‚ are designated by a capital N. Aromatic amines belong to specific families‚ which act as parent molecules. For example‚ an amino group (—NH2) attached to benzene produces the parent compound aniline. Basicity of amines Amines are basic because they possess a pair of unshared electrons‚ which they can share with other atoms. These unshared electrons create an electron density around the nitrogen atom. The greater the electron density
