In a more versatile variant, AuCl 3 catalyzes the tandem reaction in the presence of NIS to provide highly substituted heterocycles in ...
WebIntroduction. Iodination of organic compounds and the chemistry of organic iodides are of interest as major chemical fields. Their industrial application is wide 1.Iodination is one of the classical reactions of aromatic compounds and has been thoroughly investigated for both its theoretical and synthetic value. WebHence, Halogen needs the help and aid of Lewis Acidic Catalysts to activate it to become a very strong electrophile. Examples of these activated halogens are Ferric Hallides (FeX3) Aluminum Halides (AlX3) where X= Br or Cl. In the following examples, the halogen we will look at is Bromine. In the example of bromine, in order to make bromine ...
Toluene is used as a cement for fine polystyrenekits(by dissolving and then fusing surfaces) as it can be applied very precisely by brush and contains none of the bulk of an adhesive.
