2-Methylbenzophenone Me te CAS 131-58-8
He matū benzophenone te 2-Methylbenzophenone, he matū tino pai rawa atu. I taua wā anō, ko ngā ketone ngā hanganga matua o te maha o ngā ngota waro, pērā i ngā rauemi mahi, ngā kakara me ngā ngota rongoā. He mea nui ngā ketone kakara hei hanga i roto i te hanganga waro, e kitea whānuitia ana i roto i ngā hanganga matua o ngā hua taiao, ā, e whakamahia whānuitia ana i roto i ngā matū hohe koiora.

I raro i te tiakitanga o te hau kore mahi, i whakamararatia te 2-methylphenylsulfonylhydrazide (1.1 mmol), te benzonitrile (1.0 mmol), te whakakorikori palladium (2 mol %) me te biquinoline (bq, 3 mol %) ki roto i te whakarewa waro (2 mL) ), kātahi ka tāpirihia te H2O (2 mmol), ā, ka whakanuia te pāmahana ki te 80°C mō ngā hāora e 6. Kātahi ka tangohia te otinga tauhohenga e toru ngā wā ki te Et2O (5 mL), ka whakakotahihia ngā āhua waro, ā, ka whakamarokehia te whakarewa i raro i te pēhanga kua whakaitihia. Ko te hua mata i whiwhihia i tukuna ki te chromatography pou i runga i te pou silica gel (300-400 mesh), ā, ko ngā mea eluent he petroleum ether, kia whiwhi ai i te hua ūnga 2-methylbenzophenone. Ngā āhuatanga matū Kore tae, he wai mārama kōwhai mārama rānei. Ko te ira rewa he tata ki te 134°C. Whakamahia hei takawaenga rongoā.
