Web(Chloromethylene)dimethylammonium chloride is used in the synthesis of beta-lactams, n-vinyl substituted indoles and fused 2-pyridone rings and 2-azetidinones. It is used as a formylating agent and used in the preparation of anti-poxvirus agents. It is used in Staudinger reaction and Hundsdiecker-barton iododecarboxylation reaction. WebAmmonium salts are ionic compounds with the formula (R)4N + A - , where R is hydrogen, alkyl or aryl groups and A is an anion. When R is alkyl or aryl then they are referred to as quaternary ammonium salts. The quaternary ammonium cations are permanently charged, independent of the pH of their solution. Most of the ammonium salts are soluble in water …
