…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...
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...
When an electron pair donor known as a nucleophile reacts with a SP3 hybridized carbon with a good leaving group attached to it, a reaction will occur known as nucleophilic substitution. There are two main mechanisms which show how this reaction occurs. In this text we will discuss the mechan...
we have ignored another important possibility. In many cases, including the two examples above, substitution reactions compete with a type of reaction known aselimination. This will be covered in detail soon, insection 8.5.Consider, for example, the two courses that a rea...
1. The Key Pattern In A Substitution Reaction Is Breaking And Forming A New Bond At Carbon Substitution reactions are among the most versatile and important reactions in all of organic chemistry. Below are drawn three examples of these reactions.* ...
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 ...

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....
