Methyltriphenylphosphonium Bromide CAS 1779-49-3
ʻO ka Methyltriphenylphosphonium bromide he aniani keʻokeʻo. He 234-235 ℃ ka helu hehee. ʻO ka Methyltriphenylphosphonium bromide kahi paʻakai paʻakai quaternary phosphonium paʻakai pale ahi. I kēia manawa, hoʻohana nui ʻia nā mea hoʻopaʻa ahi i loko o ka halogen i nā mea hoʻopaʻa ahi kūlohelohe me nā waiwai pale ahi maikaʻi loa. Hiki ke hoʻohana ʻia lākou e like me Wittig reagents no ka hoʻomākaukau ʻana i nā olefins a me ka hoʻonui ʻana i ka helu kalapona o nā kaulahao kalapona unsaturated. Hoʻohana nui ʻia ka ylide precursor o ka hopena Wittig i ka synthesis o nā paʻa unsaturated i nā mea aniani wai. Hoʻohana nui ʻia ia i ka synthesis organik. He mea hoʻololi hoʻololi cationic maikaʻi.

1. Hoʻohui kumu o ka pane ʻana o Wittig: Hoʻohana ʻia ka Methyltriphenylphosphonium bromide e hana i nā olefins (ʻoi loa nā olefins terminal) a hoʻololi i nā aldehydes/ketones i olefins:
2. Hoʻohana nui ʻia ka Methyltriphenylphosphonium bromide i ka synthesis o nā lāʻau lapaʻau (e like me ka vitamin A, prostaglandins), nā huahana kūlohelohe (e like me nā pheromones insect) a me ka hoʻomākaukau ʻana i nā mea hana (e like me nā molekala kristal wai).
3. Phase transfer catalyst: Hoʻoikaika ka Methyltriphenylphosphonium bromide i ka hopena ma waena o ka pae wai a me ka māhele organik a hoʻomaikaʻi i ka pono o nā hopena ionic.
