Methyltriphenylphosphonium Bromide CAS 1779-49-3
Methyltriphenylphosphonium bromide jẹ kirisita funfun kan. Iyọ ojuami jẹ 234-235 ℃. Methyltriphenylphosphonium bromide jẹ iyọkuro ina phosphonium ti o ni agbara ti o lagbara. Ni lọwọlọwọ, awọn idapada ina ti o ni halogen jẹ lilo pupọju awọn imuduro ina elege pẹlu awọn ohun-ini idaduro ina to dara julọ. Wọn tun le ṣee lo bi awọn reagents Wittig fun igbaradi ti olefins ati jijẹ nọmba erogba ti awọn ẹwọn erogba unsaturated. Ipilẹṣẹ ylide ti iṣesi Wittig jẹ lilo pupọ ni iṣelọpọ ti awọn iwe ifowopamosi ti ko ni itọrẹ ninu awọn ohun elo kirisita olomi. O tun jẹ lilo pupọ ni iṣelọpọ Organic. O ti wa ni kan ti o dara cationic alakoso orilede ayase.
