Description and Uses
Methyltriphenylphosphonium bromide is used for methylenation through the Wittig reaction. It is utilized in the synthesis of an enyne and 9-isopropenyl -phenanthrene by using sodium amide as reagent. It is a lipophilic molecule and used to deliver molecules to specific cell components. Further, it acts as an antineoplastic agent.
