2-Methylbenzophenone Me CAS 131-58-8
ʻO 2-Methylbenzophenone kahi hui benzophenone, he mea koʻikoʻi loa ia. I ka manawa like, ʻo nā ketones ke kumu nui o nā molekala organik, e like me nā mea hana, nā mea ʻala a me nā molekala lāʻau. He mea koʻikoʻi nā ketone Aromatic i nā poloka hale synthetic i ka synthesis organik, ka mea nui i loko o nā hale kumu o nā huahana kūlohelohe a hoʻohana nui ʻia i nā pūhui hana biologically.

Ma lalo o ka pale o ke kinoea inert, 2-methylphenylsulfonylhydrazide (1.1 mmol), benzonitrile (1.0 mmol), palladium catalyst (2 mol%) a me biquinoline (bq, 3 mol%) ua hoʻopuehu ʻia i loko o kahi mea hoʻoheheʻe organik (2 mL) a laila. Hoʻohui ʻia ka H2O (2 mmol), a hoʻonui ʻia ka mahana i 80 ° C no 6 mau hola. A laila ua unuhi ʻia ka hopena hopena i ʻekolu manawa me ka Et2O (5 mL), ua hui pū ʻia nā mea kūlohelohe, a ua hoʻomaloʻo ʻia ka mea hoʻoheheʻe ma lalo o ke kaomi hoʻemi ʻia. ʻO ka huahana crude i loaʻa i lalo i ke kolamu chromatography ma ke kolamu silica gel (300-400 mesh), a ʻo nā eluent he petroleum ether, no ka loaʻa ʻana o ka huahana pahuhopu 2-methylbenzophenone. Nā waiwai kemika ʻAʻole waihoʻoluʻu a i ʻole melemele māmā wai aniani. ʻO ka helu hoʻoheheʻe ma kahi o 134 ° C. E hoʻohana i waena o nā lāʻau lapaʻau.
