Methyltriphenylphosphonium Bromide CAS 1779-49-3
Ko te Methyltriphenylphosphonium bromide he karaihe ma. Ko te ira whakarewa he 234-235 ℃. Ko te Methyltriphenylphosphonium bromide he tote quaternary phosphonium tote parepare mura. I tenei wa, ka whakamahia nuitia nga whakamaarama ahi-halogena hei whakamaarama mura-a-wao me nga mea tino pai mo te aukati mura. Ka taea hoki te whakamahi hei reagents Wittig mo te whakarite i nga olefins me te whakanui ake i te tau waro o nga mekameka waro haunga. Ko te ylide precursor o te tauhohenga Wittig e whakamahia nuitia ana i roto i te whakahiatotanga o nga here haunga kore i roto i nga rawa karaihe wai. Kei te whakamahia whānuitia i roto i te whakahiato waro. He pai te whakakōkī whakawhiti wāhanga cationic.

1. Tauhohenga matua o te tauhohenga Wittig: Ka whakamahia te Methyltriphenylphosphonium bromide ki te whakahiato i nga olefins (ina koa nga korefins mutunga) me te huri i nga aldehydes/ketones ki te korefins:
2. Ko te methyltriphenylphosphonium bromide e whakamahia nuitia ana i roto i te whakahiatotanga o nga raau taero (penei i te huaora A, prostaglandins), nga hua taiao (penei i nga pheromones pepeke) me te whakarite i nga taonga mahi (penei i nga ngota ngota karaihe wai).
3. Te whakakorikori o te waahanga: Ko te methyltriphenylphosphonium bromide e whakatairanga ana i te tauhohenga i waenga i te wahanga wai me te wahanga waro me te whakapai ake i te pai o nga tauhohenga katote.
