Methyltriphenylphosphonium Bromide CAS 1779-49-3
Methyltriphenylphosphonium bromide ke kristale e tšoeu. Sebaka se qhibilihang ke 234-235 ℃. Methyltriphenylphosphonium bromide ke sekontiri se tiileng sa quaternary phosphonium salt flame retardant. Hajoale, li-halogen-containing flame retardants li sebelisoa haholo li-organic flame retardants tse nang le thepa e ntle haholo e thibelang lelakabe. Li ka sebelisoa hape e le li-reagents tsa Wittig bakeng sa ho lokisa li-olefin le ho eketsa palo ea khabone ea liketane tsa khabone tse unsaturated. Selelekela sa ylide sa karabelo ea Wittig se sebelisoa haholo ho kopanngoeng ha li-unsaturated bond ka thepa ea kristale ea metsi. E boetse e sebelisoa haholo ho organic synthesis. Ke ntho e ntle ea cationic phase transition catalyst.

1. Core reagent ea Wittig reaction: Methyltriphenylphosphonium bromide e sebelisoa ho kopanya olefin (haholo-holo terminal olefin) le ho fetola aldehydes/ketones ho olefin:
2. Methyltriphenylphosphonium bromide e sebelisoa haholo ha ho etsoa lithethefatsi (tse kang vithamine A, prostaglandins), lihlahisoa tsa tlhaho (tse kang li-pheromone tsa likokoanyana) le ho lokisetsa lisebelisoa tse sebetsang (tse kang limolek'hule tsa kristale ea metsi).
3. Phase ea phetisetso ea Phase: Methyltriphenylphosphonium bromide e khothalletsa karabelo pakeng tsa karolo ea metsi le karolo ea manyolo le ho ntlafatsa katleho ea liketso tsa ionic.
