Tetraphenylphosphine bromide wani fili ne na kwayoyin halitta. Mai zuwa shine gabatarwa ga kaddarorin, amfani, hanyoyin shiri da bayanan aminci na tetraphenylphosphine bromide:

inganci:

- Tetraphenylphosphine bromide kristal ne mara launi ko fari mai kauri.

- Mai narkewa a cikin abubuwan kaushi na halitta kamar ethers da chlorinated hydrocarbons, maras narkewa a cikin ruwa.

- Yana da tushe mai ƙarfi na Lewis wanda zai iya samar da gine-gine tare da karafa da yawa.

Amfani:

- Tetraphenylphosphine bromide ana amfani dashi ko'ina azaman reagent sinadarai a cikin haɓakar kwayoyin halitta.

- Ana iya amfani dashi azaman ligand karfen canji kuma yana shiga cikin halayen catalytic.

- Ana amfani da shi a cikin haɗin gwiwar kwayoyin halitta don ƙari na mahadi na carbonyl da acid carboxylic, da kuma don amsawar amination da conjugate ƙari na olefins.

Hanya:

- Ana iya shirya tetraphenylphosphine bromide ta hanyar amsa tetraphenylphosphine tare da hydrogen bromide.

- Yawancin lokaci yana amsawa a cikin abubuwan kaushi na halitta kamar ether ko toluene.

- Sakamakon tetraphenylphosphine bromide za a iya ƙara yin crystallized don samar da samfur mai tsabta.

Bayanin Tsaro:
