2-Methylbenzophenone Me CAS 131-58-8
He hui benzophenone ka 2-Methylbenzophenone, he kemika maikaʻi loa ia. I ka manawa like, ʻo nā ketones kekahi mau ʻano hana nui o nā molekala organik he nui, e like me nā mea hana, nā mea ʻala a me nā molekala lāʻau. He mea nui loa nā ketones ʻala i nā poloka hale synthetic i ka synthesis organik, kahi i loaʻa nui i nā ʻano hana nui o nā huahana kūlohelohe a hoʻohana nui ʻia i nā hui biologically active.

Ma lalo o ka pale o ke kinoea inert, ua hoʻopuehu ʻia ka 2-methylphenylsulfonylhydrazide (1.1 mmol), benzonitrile (1.0 mmol), palladium catalyst (2 mol%) a me biquinoline (bq, 3 mol%) i loko o kahi mea hoʻoheheʻe organik (2 mL) ), a laila ua hoʻohui ʻia ʻo H2O (2 mmol), a ua hoʻokiʻekiʻe ʻia ka mahana i 80°C no 6 mau hola. A laila ua unuhi ʻia ka hopena hopena ʻekolu manawa me Et2O (5 mL), ua hui pū ʻia nā ʻāpana organik, a ua hoʻomaloʻo ʻia ka mea hoʻoheheʻe ma lalo o ke kaomi i hoʻemi ʻia. Ua hoʻokomo ʻia ka huahana maka i loaʻa i ka chromatography kolamu ma kahi kolamu silica gel (300-400 mesh), a ʻo nā eluents he petroleum ether, e loaʻa ai ka huahana pahuhopu 2-methylbenzophenone. Nā waiwai kemika ʻAʻohe kala a wai melemele māmā paha. ʻO ke kiko heheʻe ma kahi o 134°C. E hoʻohana ma ke ʻano he waena lāʻau lapaʻau.
