용도

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.

참고

Hygroscopic. Incompatible with strong oxidizing agents.

참조 문헌

Precursor of Wittig ylide for methylenation of carbonyl compounds (see Appendix 1). See, e.g.: Org. Synth. Coll., 5, 751 (1973). A simplified procedure using K2CO3 in triglyme has been reported: Synth. Commun., 22, 513 (1992).

Where the ylide is insufficiently reactive, a further proton can be removed by s-BuLi or t-BuLi, and the resulting lithio ylide reacted with hindered ketones such as fenchone: J. Am. Chem. Soc., 104, 4724 (1982). Reaction of the lithio ylide with an epoxide generates a new ylide, with which Wittig olefination of aldehydes gives trans-homoallylic alcohols (same ref.):
