Methyltriphenylphosphonium Bromide CAS 1779-49-3
Methyltriphenylphosphonium bromide o se tioata paepae. O le mea e liusuavai ai e 234-235 ℃. Methyltriphenylphosphonium bromide ose quaternary phosphonium masima masima fa'aluma. I le taimi nei, o lo'o fa'aogaina mea fa'afefe mu o lo'o i ai halogen fa'aogaina fa'aola afi fa'atasi ai ma mea e sili ona lelei e fa'afefe mu. E mafai foi ona faʻaaogaina e fai ma Wittig reagents mo le saunia o olefins ma faʻateleina le numera kaponi o filifili carbon unsaturated. O le ylide precursor o le tali Wittig e masani ona faʻaaogaina i le tuʻufaʻatasia o fusi e leʻi tuʻuina i mea tioata vai. E fa'aaoga lautele fo'i i le fa'aogaina o meaola. O se fa'ato'aga lelei o le suiga o vaega cationic.

1. Reagent autu o le tali a Wittig: Methyltriphenylphosphonium bromide e faʻaaogaina e faʻapipiʻi ai olefins (aemaise ole olefins terminals) ma liliu aldehydes/ketones i olefins:
2. Methyltriphenylphosphonium bromide o loʻo faʻaaogaina lautele i le tuʻufaʻatasia o vailaʻau (e pei o le vaitamini A, prostaglandins), mea faʻanatura (e pei o pheromones iniseti) ma le sauniuniga o mea aoga (e pei o mole tioata tioata vai).
3. Fa'asologa o le fa'asologa o le vaega: Methyltriphenylphosphonium bromide e fa'aolaina ai le tali atu i le va o le vaega vai ma le vaega fa'alenatura ma fa'aleleia atili ai le lelei o gaioiga fa'aona.
