2-Methylbenzophenone NeCAS 131-58-8
2-Methylbenzophenone inhengo yebenzophenone, iyo inonyanya kukosha kemikari yakanaka. Panguva imwecheteyo, ketoni zvakare ndiwo musimboti zvimiro zveakawanda organic mamorekuru, akadai seanoshanda zvinhu, zvinonhuhwirira uye mamorekuru ezvinodhaka. Maketone anonhuhwirira akakosha zvikuru ekugadzira zvidhinha muorganic synthesis, ayo anowanikwa zvakanyanya mupakati zvimiro zvezvigadzirwa zvechisikigo uye anoshandiswa zvakanyanya mubiologically inoshanda makomisheni.

Pasi pekuchengetedzwa kwegasi inert, 2-methylphenylsulfonylhydrazide (1.1 mmol), benzonitrile (1.0 mmol), palladium catalyst (2 mol %) uye biquinoline (bq, 3 mol %) akaparadzirwa mune organic solvent (2 mL)), ipapo. H2O (2 mmol) yakawedzerwa, uye tembiricha yakasimudzwa kusvika pa80°C kwemaawa matanhatu. Zvadaro mhinduro yemhinduro yakatorwa katatu neEt2O (5 mL), zvikamu zvehupenyu zvakabatanidzwa, uye solvent yakasundwa-yakaomeswa pasi pekumanikidzwa kwakaderedzwa. Chigadzirwa chisina kuchena chakawanikwa chakaiswa pasi pekoramu chromatography pane silica gel column (300-400 mesh), uye eruents aive petroleum ether, kuti awane chinongedzo chigadzirwa 2-methylbenzophenone. Chemical properties isina ruvara kana chiedza yero inoonekera mvura. Nzvimbo yekunyunguduka inenge 134°C. Shandisa semushonga wepakati.
