Fa'aaogāga
Burgess fa'amama vai, e ta'ua fo'i le Burgess reagent, o le methyl N-(triethylaminosulfuryl) carbamate.E mafai ona fa'amama le vai i lalo o tulaga malu ma ose mea e fa'amama le fa'asusu.E fa'aaogaina e fa'aliliu ai 'ava mālosi lona lua ma 'ava mālosi fa'atasi ma protons e lata ane i alkenes.
E mafai ona saunia e ala ile tali ole chlorosulfone isocyanate ma triethylamine ile methanol.I le taimi o le faʻamaʻaina, e osofaʻia le sulfur e le hydroxyl group, ona tupu ai lea o le faʻaumatiaina o cis.E mafai fo'i ona fa'aoga mea e fa'amama ai le vai a Burgess e fa'aputu ai fa'aputuga isonitrile mai le formamide.O le faiga o le tali e tutusa ma le xanthate elimination reaction, ma o le alkene e maua foi i le cis elimination o le suiga o le tulaga o le mama e ono i totonu o le mole.
Fa'aputuina & Teuina
