2-Methylbenzophenone Faatasi ai ma CAS 131-58-8
2-Methylbenzophenone o se vailaʻau benzophenone, o se vailaʻau sili ona taua. I le taimi lava e tasi, o ketones foi o fausaga autu o le tele o meaola faʻalaʻau, e pei o mea aoga, mea manogi ma vailaʻau vailaʻau. O ketone manogi o ni poloka fau fale e sili ona taua i le faʻaogaina o meaola, lea o loʻo i ai lautele i totonu o fausaga autu o oloa faʻanatura ma e faʻaaogaina lautele i mea ola faʻapitoa.

I lalo o le puipuiga o le kasa inert, 2-methylphenylsulfonylhydrazide (1.1 mmol), benzonitrile (1.0 mmol), palladium catalyst (2 mol%) ma le biquinoline (bq, 3 mol%) na salalau i totonu o se solvent organic (2 mL) ), Na faaopoopo H2O (2 mmol), ma siitia le vevela i le 80°C mo le 6 itula. Ona fa'atolu lea ona aveese mai le vaifofo o le tali i le Et2O (5 mL), fa'atasi ai vaega fa'aola, ma fa'amamago le solvent i lalo o le fa'aitiitia o le mamafa. O le oloa fa'atauva'a na maua na tu'uina atu i le chromatography koluma i luga o se koluma gel silica (300-400 mesh), ma o mea e fa'aaogaina o le suau'u eter, e maua ai le oloa fa'atatau 2-methylbenzophenone. O mea tau vaila'au E leai se lanu pe lanu samasama malamalama vai. O le mea liusuavai e tusa ma le 134°C. Fa'aaogā e fai ma vaila'au fa'alatalata.
