Thermally and photochemically induced substitution reactions between 2-methoxy-1,4-naphthoquinone and methylamine follow different pathways with high regiospecificity: thermal reaction results in replacement of the 2-methoxy group by the amine, whereas photosubstitution involves replacement of hydrogen at the 3-position 2,6-dimethoxy. Abstract nucleophilic substitution reactions are something that is quite important when studying organic chemistry nucleophilic substitution is something that interests chemists because by using nucleophilic substitution, they can transform functional groups into organic compounds. Reactions of aromatic compounds a student should be able to: 1 predict the product(s) of electrophilic aromatic substitution (eas), nucleophilic. Alkyl halides undergo many reactions in which a nucleophile displaces the halogen atom bonded to the central carbon of the molecule the displaced halogen atom becomes a halide ion some typical nucleophiles are the hydroxy group ( − oh), the alkoxy group (ro −), and the cyanide ion ( − c n.

First-order nucleophilic substitution: the carbon-ligand bond is cleaved independently, forming an anion (nucleofuge) and a carbocation (a))the attack of the nucleophile on the carbocation then yields the substitution product (b).
