One important type of chemical reaction is the nucleophilic substitution reaction, which occurs when a nucleophile replaces another nucleophile bound to an atom in a molecule. Nucleophiles are atoms that bind with other atoms by donating a pair of electrons, as they will be negatively charged when...
…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...
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....
