Methyltriphenylphosphonium Bromide CAS 1779-49-3
Methyltriphenylphosphonium bromide farin crystal ne. Matsayin narkewa shine 234-235 ℃. Methyltriphenylphosphonium bromide shine m quaternary phosphonium gishiri retardant. A halin yanzu, masu kare harshen wuta mai ƙunshe da halogen ana amfani da su ko'ina tare da kyawawan kaddarorin kashe wuta. Hakanan za'a iya amfani da su azaman reagents na Wittig don shirye-shiryen olefins da haɓaka adadin carbon na sarƙoƙin carbon da ba a cika ba. Ana amfani da precursor na ylide na amsawar Wittig a cikin haɗin haɗin da ba a cika ba a cikin kayan kristal na ruwa. Har ila yau, ana amfani da shi sosai a cikin kwayoyin halitta. Yana da kyau cationic lokaci mika mulki mai kara kuzari.
