Methyltriphenylphosphonium Bromide CAS 1779-49-3
Methyltriphenylphosphonium bromide ndi kristalo woyera. Malo osungunuka ndi 234-235 ℃. Methyltriphenylphosphonium bromide ndi cholimba cha quaternary phosphonium salt retardant. Pakadali pano, zoziziritsa moto zokhala ndi halogen zimagwiritsidwa ntchito kwambiri ndi organic flame retardants okhala ndi mphamvu zabwino kwambiri zoletsa malawi. Atha kugwiritsidwanso ntchito ngati ma reagents a Wittig pokonzekera ma olefins ndikuwonjezera kuchuluka kwa kaboni waunyolo wa carbon unsaturated. Kalambulabwalo wa ylide wa machitidwe a Wittig amagwiritsidwa ntchito kwambiri popanga zomangira zopanda unsaturated muzinthu zamadzimadzi za kristalo. Amagwiritsidwanso ntchito kwambiri mu organic synthesis. Ndiwothandizira wabwino wa cationic phase transition.

1. Core reagent of Wittig reaction: Methyltriphenylphosphonium bromide imagwiritsidwa ntchito kupanga olefins (makamaka terminal olefins) ndikusintha aldehydes/ketones kukhala olefins:
2. Methyltriphenylphosphonium bromide imagwiritsidwa ntchito kwambiri popanga mankhwala (monga vitamini A, prostaglandins), zinthu zachilengedwe (monga ma pheromones a tizilombo) komanso kukonza zinthu zogwirira ntchito (monga mamolekyu amadzimadzi amadzimadzi).
3. Chothandizira kutengerapo gawo: Methyltriphenylphosphonium bromide imalimbikitsa kuchitapo kanthu pakati pa gawo lamadzi ndi gawo lachilengedwe ndikuwongolera magwiridwe antchito a ionic.
