2-Methylbenzophenone Ndi CAS 131-58-8
2-Methylbenzophenone ndi mankhwala a benzophenone, omwe ndi mankhwala abwino kwambiri. Panthawi imodzimodziyo, matupi a ketoni ndiwonso maziko a mamolekyu ambiri a organic, monga zipangizo zogwirira ntchito, zonunkhira ndi mamolekyu a mankhwala. Ma ketoni onunkhira ndizofunikira kwambiri zomangira zomangira mu organic synthesis, zomwe zimapezeka kwambiri m'mapangidwe achilengedwe azinthu zachilengedwe ndipo zimagwiritsidwa ntchito kwambiri mumagulu achilengedwe.

Pansi pa chitetezo cha mpweya wa inert, 2-methylphenylsulfonylhydrazide (1.1 mmol), benzonitrile (1.0 mmol), palladium chothandizira (2 mol%) ndi biquinoline (bq, 3 mol %) anamwazikana mu zosungunulira organic (2 mL)), ndiye H2O (2 mmol) anawonjezedwa kwa 8 hours. Ndiye yankho anachita anali yotengedwa katatu ndi Et2O (5 mL), ndi organic magawo anali pamodzi, ndi zosungunulira anali sapota-zouma pansi mavuto afupika. Zomwe zinapezedwa zidapangidwa ndi chromatography pazanja la gel osakaniza (300-400 mesh), ndipo zowoneka bwino zinali mafuta a petroleum ether, kuti apeze zomwe chandamale 2-methylbenzophenone. Mankhwala katundu Zopanda mtundu kapena kuwala chikasu mandala madzi. Malo osungunuka ndi pafupifupi 134 ° C. Gwiritsani ntchito ngati mankhwala apakatikati.
