Methyltriphenylphosphonium Bromide CAS 1779-49-3
Methyltriphenylphosphonium bromide bụ kristal ọcha. Ebe mgbaze bụ 234-235 ℃. Methyltriphenylphosphonium bromide bụ ihe na-egbochi ire ọkụ nke phosphonium nke anọ. Ka ọ dị ugbu a, a na-eji ọkụ retardants nwere halogen eme ihe n'ọtụtụ ebe nwere ihe na-egbochi ire ọkụ. Enwere ike iji ha dị ka Wittig reagents maka nkwadebe olefin na ịbawanye ọnụ ọgụgụ carbon nke ụdọ carbon unsaturated. A na-eji ylide precursor nke mmeghachi omume Wittig eme ihe n'ọtụtụ ebe na njikọta nke agbụ na-enweghị ike na ihe kristal mmiri mmiri. A na-ejikwa ya eme ihe n'ọtụtụ ebe na njikọ organic. Ọ bụ ezigbo cationic na-eme mgbanwe mgbanwe.

1. Core reagent nke Wittig mmeghachi omume: Methyltriphenylphosphonium bromide na-eji synthesize olefins (karịsịa ọnụ olefins) na tọghata aldehydes / ketones n'ime olefins:
2. Methyltriphenylphosphonium bromide na-ejikarị eme ihe na njikọ nke ọgwụ (dịka vitamin A, prostaglandins), ngwaahịa ndị sitere n'okike (dị ka pheromones ụmụ ahụhụ) na nkwadebe nke ihe ndị na-arụ ọrụ (dị ka mkpụrụ ndụ kristal mmiri mmiri).
3. Ntugharị na-enyefe oge: Methyltriphenylphosphonium bromide na-akwalite mmeghachi omume n'etiti oge mmiri na akụkụ nke organic ma mee ka arụmọrụ nke mmeghachi omume ionic dịkwuo mma.
