2-Methylbenzophenone Ndi CAS 131-58-8
2-Methylbenzophenone ndi mankhwala a benzophenone, omwe ndi mankhwala abwino kwambiri. Nthawi yomweyo, matupi a ketoni ndizomwe zimapangidwira mamolekyu ambiri achilengedwe, monga zida zogwirira ntchito, zonunkhira ndi mamolekyu amankhwala. 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.
