2-Methylbenzophenone hamwe na CAS 131-58-8
2-Methylbenzophenone ni ikinyabutabire cya benzophenone, kikaba ari ikintu cy’ingenzi cyane. Muri icyo gihe, ketones nazo ni imiterere y’ingenzi ya molekile nyinshi z’umwimerere, nk’ibikoresho bikora, impumuro nziza n’imiti. Ketones zihumura neza ni ingenzi cyane mu gukora synthetic synthesis, ziboneka cyane mu miterere y’ibanze y’ibikomoka ku bimera karemano kandi zikoreshwa cyane mu bintu bikora ku binyabuzima.

Mu kurinda umwuka udafite imyuka, 2-methylphenylsulfonylhydrazide (1.1 mmol), benzonitrile (1.0 mmol), palladium catalyst (2 mol %) na biquinoline (bq, 3 mol %) byajugunywe mu kintu cy’umwimerere (2 mL) ), hanyuma H2O (2 mmol) yongerwaho, maze ubushyuhe buzamuka bugera kuri 80°C mu gihe cy’amasaha 6. Hanyuma umuti w’ibizamini wakuwemo inshuro eshatu hamwe na Et2O (5 mL), ibice by’umwimerere birahuzwa, maze umuti wumisha unyuzwa ku gitutu gito. Umusaruro wabonetse wakorewe kuri chromatography y’inkingi ku nkingi ya silica gel (mesh 300-400), maze imirasire yari peteroli ether, kugira ngo haboneke umusaruro wa 2-methylbenzophenone. Imiterere ya chimique idafite ibara cyangwa umuhondo woroshye ubonerana. Aho gushonga ni hafi 134°C. Koresha nk'umuti uhuza imiti.
