SRN1 Mechanism in Heteroaromatic Nucleophilic Substitution. Reactions Involving Certain Dihalogenated ?-Deficient Nitrogen Heterocycles
Photostimulated reactions of 2,6-,2,3-, 3,5-, and 2,5-dihalopyridines (1a-e) with pinacolone potassium enolate (2) in liquid NH3 lead to facile replacement of both halogens via a modified SRN1 mechanism, which does not involve intermediate formation of monosubstitution products.The potassium salts of phenylacetonitrile (12a) and alpha-ethylphenylacetonitrile (12b) react with 2,6-dibromopyridine (1a) under similar conditions to afford a mixture of mono- and disubstituted products via a related SRN1 process. 4,7-Dichloroquinoline (16) undergoes radical-chain displacement of chloride from C4 with enolate 2. 2,6-Dichloropyrazine (18) and 2,3-dichloropyrazine (20) also undergo monosubstitution with 2 and diisopropyl ketone potassium enolate (22), but these reactions appear to be mainly addition-elimination (SNAr) processes.Treatment of 3,6-dichloropyridazine (27) with 22 results in addition of 22 to C4 of the substrate.Photoassisted reaction of 2,4-dichloropyrimidine (31) with 12a leads to exclusive chloride displacement from C4 via the SRN1 mechanism.
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 141-30-0
