An SN1 reaction is a nucleophilic substitution reaction where the leaving nucleophile disassociates, and the attacking nucleophile binds the molecule in two separate steps, creating a stable carbon cation intermediate. An example of an SN1 reaction is the hydrolysis of tert-butyl bromide with water...

Conditions required for nucleophilic substitution reactions to occur are: (1) the presence of nucleophiles (Lewis bases) which in silicate melts are bridging oxygen (BO), non-bridging oxygen (NBO) and free oxygen (O); (2) the presence of tetrahedra (Q species) with strongly electrophilic ...
1)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.According to tea...
ipso-Nucleophilic aromatic substitution of the nitro group by fluoride anions can be used for the synthesis of the 18F-labeled compounds. This reaction requires the presence of electron-withdrawing groups (e.g., carbonyl) at ortho or para positions to the nitro group to stabilize the intermediate...
Lewis acids can make electrophiles even more electron-poor(reactive), increasing the reaction rate. For example FeBr3/ Br2allows bromination to occur at a useful rate on benzene, whereas Br2by itself is slow). Everything we’ve learned so far about substitution on aromatic rings would teach ...

I have a question on the Halogen addition reaction, if the alkene is irregular, i.e one side of the double bond differs from the other, and the bond is Trans (E) is there still only 1 product formed? (the wikipedia example only shows a symettrical alkene)I ask this because i checke...
