Tom ntej: Methyltriphenylphosphonium Bromide CAS 1779-49-3
Methyltriphenylphosphonium bromide yog siv lead ua dawb. Melting point yog 234-235 ℃. Methyltriphenylphosphonium bromide yog ib qho khoom quaternary phosphonium ntsev nplaim taws retardant. Tam sim no, halogen-muaj nplaim retardants tau dav siv cov nplaim hluav taws kub nyhiab nrog cov nplaim hluav taws zoo heev. Lawv kuj tuaj yeem siv los ua Wittig reagents rau kev npaj ntawm olefins thiab ua kom cov pa roj carbon ntau ntawm cov saw hlau tsis zoo. Lub ylide precursor ntawm Wittig cov tshuaj tiv thaiv yog dav siv nyob rau hauv lub synthesis ntawm unsaturated bonds nyob rau hauv cov ntaub ntawv siv lead ua kua. Nws kuj yog siv dav hauv cov organic synthesis. Nws yog ib qho zoo cationic theem hloov catalyst.

1. Core reagent ntawm Wittig cov tshuaj tiv thaiv: Methyltriphenylphosphonium bromide yog siv los ua ke olefins (tshwj xeeb tshaj yog terminal olefins) thiab hloov aldehydes / ketones rau hauv olefins:
2. Methyltriphenylphosphonium bromide yog dav siv nyob rau hauv cov synthesis ntawm cov tshuaj (xws li vitamin A, prostaglandins), tej yam ntuj tso khoom (xws li kab pheromones) thiab kev npaj cov khoom siv (xws li kua siv lead ua molecules).
3. Theem hloov catalyst: Methyltriphenylphosphonium bromide txhawb cov tshuaj tiv thaiv ntawm cov theem aqueous thiab cov organic theem thiab txhim kho kev ua tau zoo ntawm cov tshuaj tiv thaiv ionic.
