Methyltriphenylphosphonium Bromide CAS 1779-49-3
Methyltriphenylphosphonium bromide ikristaro chena. Melting point ndeye 234-235 ℃. Methyltriphenylphosphonium bromide is solid quaternary phosphonium salt flame retardant. Parizvino, halogen-ine maflame retardants anoshandiswa zvakanyanya organic flame retardants ane yakanakisa murazvo inodzoreredza zvimiro. Iwo anogona zvakare kushandiswa seWittig reagents kugadzirira olefins uye kuwedzera kabhoni nhamba yeunsaturated kabhoni maketani. Iyo ylide precursor yeWittig reaction inoshandiswa zvakanyanya mukugadzirwa kweunsaturated bond mune yemvura crystal zvinhu. Inoshandiswawo zvakanyanya muorganic synthesis. Iyo yakanaka cationic phase transition catalyst.

1. Core reagent yeWittig reaction: Methyltriphenylphosphonium bromide inoshandiswa kugadzira olefins (kunyanya terminal olefins) uye kushandura aldehydes/ketones kuita olefins:
2. Methyltriphenylphosphonium bromide inoshandiswa zvakanyanya mukugadzirwa kwemishonga (yakadai sevhitamini A, prostaglandins), zvigadzirwa zvechisikigo (sezvipembenene pheromones) uye kugadzirirwa kwezvinhu zvinoshanda (zvakadai semvura crystal molecules).
3. Phase transfer catalyst: Methyltriphenylphosphonium bromide inokurudzira kugadzirisa pakati pechikamu chemvura uye chikamu chehupenyu uye inovandudza kushanda kweiyo ionic.
