Methyltriphenylphosphonium Bromide CAS 1779-49-3
Methyltriphenylphosphonium bromide waa crystal cad. Barta dhalaalka waa 234-235 ℃. Methyltriphenylphosphonium bromide waa fosfonium quaternary adag oo dib u celisa ololka milixda. Waqtigan xaadirka ah, dab-celiyayaasha ololka ee halogen ka kooban ayaa si weyn loo isticmaalaa dib-u-celinta ololka dabiiciga ah oo leh sifooyin dib-u-celin aad u wanaagsan. Waxa kale oo loo isticmaali karaa sida reagents Wittig si loogu diyaariyo olefins iyo kordhinta tirada kaarboon ee silsiladaha kaarboonka aan saturated. Horudhaca ylide ee falcelinta Wittig ayaa si weyn loogu isticmaalaa isku dhafka curaarta aan saturated ee walxaha crystal dareeraha ah. Waxa kale oo si weyn loogu isticmaalaa isku-dhafka organic. Waa kicinta marxaladda cationic wanaagsan.

1. Reagent Core of Wittig reaction: Methyltriphenylphosphonium bromide waxaa loo isticmaalaa in lagu sameeyo olefins (gaar ahaan olefins terminal) oo loogu badalo aldehydes/ketones olefins:
2. Methyltriphenylphosphonium bromide waxaa si weyn loogu isticmaalaa isku-darka daawooyinka (sida fitamiin A, prostaglandins), alaabta dabiiciga ah (sida pheromones cayayaanka) iyo diyaarinta qalabka shaqada (sida dareeraha crystal molecules).
3. Xakamaynta wareejinta wejiga: Methyltriphenylphosphonium bromide waxay kor u qaadaysaa falcelinta u dhaxaysa wejiga aqueous iyo wejiga organic waxayna hagaajinaysaa waxtarka falcelinta ionic.
