Methyltriphenylphosphonium Bromide CAS 1779-49-3
Methyltriphenylphosphonium bromide minangka kristal putih. Titik lebur yaiku 234-235 ℃. Methyltriphenylphosphonium bromide minangka bahan tahan api uyah fosfonium kuarterner sing padhet. Saiki, retardants api sing ngemot halogen digunakake minangka bahan tahan api organik kanthi sifat tahan api sing apik banget. Dheweke uga bisa digunakake minangka reagen Wittig kanggo nyiapake olefin lan nambah jumlah karbon rantai karbon ora jenuh. Prekursor ylide saka reaksi Wittig akeh digunakake ing sintesis ikatan tak jenuh ing bahan kristal cair. Iki uga akeh digunakake ing sintesis organik. Iki minangka katalis transisi fase kationik sing apik.

1. Reagen inti reaksi Wittig: Methyltriphenylphosphonium bromide digunakake kanggo nyintesis olefin (utamane olefin terminal) lan ngowahi aldehida/keton dadi olefin:
2. Methyltriphenylphosphonium bromide digunakake akeh ing sintesis obat (kayata vitamin A, prostaglandin), produk alami (kayata feromon serangga) lan nyiapake bahan fungsional (kayata molekul kristal cair).
3. Katalis transfer fase: Methyltriphenylphosphonium bromide ningkatake reaksi antarane fase banyu lan fase organik lan ningkatake efisiensi reaksi ion.
