nucleophilicsubstitutionreactions
There are 2 types of Nucleophilic Substitution Reactions: SN1 & SN2, each having its own mechanism. The SN2 reaction is usually learned first. S stands for “Substitution”; N stands for “Nucleophilic”; and 1 or 2 refers to the reaction’s “Molecularity”: whether the RATE of the react...
…of reaction is known as nucleophilic substitution. Examples of nucleophilic reagents are the halogen anions (Cl-, Br-, I-), ammonia (NH3), the hydroxyl group, the alkoxy group (RO−), the cyano group, and the hydrosulfide group. In the second type of substitution reaction, the substitu...

3) Nucleophilic substitution reaction 亲核取代反应 1. Aripiprazole in overall yield of 68% was synthesized from 2,3-dichloroaniline by a three-step nucleophilic substitution reaction in yield of 83%,91% and 90%,respectively. 以2,3-二氯苯胺为原料,经3步亲核取代反应合成了阿立哌唑。 2. Accord...
摘要: A novel nucleophilic substitution reaction at the nitrogen of arylsulfonamides by means of phosphide anions has been described. This reaction allows for the efficient transformation of arylsulfonamides into synthetically valuable phosphamides, amines, and a variety of protected amines....
The Two Reactive Partners In A Substitution Reaction Are An Electron-Rich “Nucleophile” And An Electron-Poor “Electrophile” Substitution Reactions Resemble Acid-Base Reactions, Except That A Bond Forms And Breaks At Carbon Instead Of H+
