I-2-Methylbenzophenone ene-CAS 131-58-8
I-2-Methylbenzophenone yi-benzophenone compound, eyikhemikhali entle ebaluleke kakhulu. Kwangaxeshanye, ii-ketones zikwayizona zakhiwo ziphambili zeemolekyuli ezininzi ze-organic, ezifana nezixhobo ezisebenzayo, iziqholo kunye neemolekyuli zamayeza. Ii-ketones ezinuka kamnandi zizinto ezibaluleke kakhulu zokwakha ezenziweyo kwi-organic synthesis, ezikhoyo kakhulu kwizakhiwo ezingundoqo zeemveliso zendalo kwaye zisetyenziswa kakhulu kwiikhompawundi ezisebenzayo kwi-biology.

Phantsi kokhuseleko lwegesi engasebenziyo, i-2-methylphenylsulfonylhydrazide (1.1 mmol), i-benzonitrile (1.0 mmol), i-palladium catalyst (2 mol %) kunye ne-biquinoline (bq, 3 mol %) zasasazwa kwi-organic solvent (2 mL) ), emva koko kongezwa i-H2O (2 mmol), kwaye ubushushu baphakanyiswa ukuya kwi-80°C kangangeeyure ezi-6. Emva koko isisombululo se-reaction sakhutshwa kathathu nge-Et2O (5 mL), ii-organic phases zadityaniswa, kwaye i-solvent yomiswa nge-spin phantsi koxinzelelo oluncitshisiweyo. Imveliso ekrwada efunyenweyo yafakwa kwi-column chromatography kwikholamu ye-silica gel (300-400 mesh), kwaye ii-eluents yayiyi-petroleum ether , ukuze kufunyanwe imveliso ekujoliswe kuyo i-2-methylbenzophenone. Iipropati zeekhemikhali Ulwelo olungenambala okanye olutyheli olukhanyayo olucacileyo. Iqondo lokunyibilika limalunga ne-134°C. Sebenzisa njenge-pharmaceutical intermediate.
