Iyini i-2-Methylbenzophenone Nge-CAS 131-58-8?

I-2-Methylbenzophenone iyinhlanganisela ye-benzophenone, okuyikhemikhali enhle ebaluleke kakhulu. Ngesikhathi esifanayo, ama-ketone nawo ayizimo eziyinhloko zama-molecule amaningi e-organic, njengezinto ezisebenzayo, amakha nama-molecule ezidakamizwa. Ama-ketones anephunga elimnandi abaluleke kakhulu amabhlogo wokwakha okwenziwa ku-organic synthesis, atholakala kabanzi ezakhiweni eziwumgogodla wemikhiqizo yemvelo futhi asetshenziswa kabanzi kumakhompiyutha asebenzayo we-biologically.

Isicelo

Ngaphansi kokuvikelwa kwegesi ye-inert, i-2-methylphenylsulfonylhydrazide (1.1 mmol), i-benzonitrile (1.0 mmol), i-palladium catalyst (2 mol %) ne-biquinoline (bq, 3 mol %) yahlakazwa ku-solvent yemvelo (2 mL)), bese I-H2O (2 mmol) yengezwe, futhi izinga lokushisa lakhuphuka lafika ku-80°C amahora angu-6. Khona-ke isisombululo sokusabela sakhishwa izikhathi ezintathu nge-Et2O (5 mL), izigaba ze-organic zahlanganiswa, futhi i-solvent yaphonswa ngaphansi kwengcindezi encishisiwe. Umkhiqizo ongahluziwe otholiwe ufakwe ngaphansi kwekholomu ye-chromatography kukholomu yejeli ye-silica (300-400 mesh), futhi ama-ethers kwakuyi-petroleum ether, ukuze kutholwe umkhiqizo ohlosiwe we-2-methylbenzophenone. Izakhiwo zamakhemikhali Uketshezi olungenambala noma oluphuzi olukhanyayo olusobala. Indawo yokuncibilika icishe ibe ngu-134°C. Sebenzisa njengengxenye yezemithi.
