Iyini i-Methyltriphenylphosphonium Bromide CAS 1779-49-3?

I-Methyltriphenylphosphonium bromide iyikristalu emhlophe. Iphuzu elincibilikayo lingu-234-235 ℃. I-Methyltriphenylphosphonium bromide iyisici esiqinile se-quaternary phosphonium salt flame retardant. Njengamanje, ama-halogen-aqukethe ama-flame retardants asetshenziswa kabanzi ama-organic flame retardants anezakhiwo ezinhle kakhulu zokubushela ilangabi. Angasetshenziswa futhi njengama-reagents e-Wittig ekulungiseni ama-olefin nokwandisa inani lekhabhoni lamaketanga ekhabhoni engagcwalisiwe. Isandulela se-ylide sokusabela kwe-Wittig sisetshenziswa kakhulu ekuhlanganiseni amabhondi angagcwele ezintweni zekristalu ewuketshezi. Ibuye isetshenziswe kabanzi ku-organic synthesis. Kuyi-catalyst enhle ye-cationic phase transition.

Isicelo

1. I-Reagent eyinhloko yokusabela kwe-Wittig: I-Methyltriphenylphosphonium bromide isetshenziselwa ukuhlanganisa ama-olefin (ikakhulukazi ama-olefin abulalayo) nokuguqula ama-aldehydes/ketone abe ama-olefin:

2. I-Methyltriphenylphosphonium bromide isetshenziswa kakhulu ekuhlanganisweni kwezidakamizwa (ezifana ne-vitamin A, i-prostaglandin), imikhiqizo yemvelo (njengama-pheromone ezinambuzane) kanye nokulungiswa kwezinto zokusebenza (njengama-molecule e-crystal ewuketshezi).

3. I-catalyst yokudlulisa isigaba: I-Methyltriphenylphosphonium bromide ikhuthaza ukusabela phakathi kwesigaba samanzi kanye nesigaba sezinto eziphilayo futhi ithuthukise ukusebenza kahle kokusabela kwe-ionic.
