2-Methylbenzophenone oo leh CAS 131-58-8
2-Methylbenzophenone waa isku-dhafka benzophenone, kaas oo ah kiimiko wanaagsan oo aad muhiim u ah. Isla mar ahaantaana, ketones sidoo kale waa qaab-dhismeedka asaasiga ah ee unugyo dabiici ah oo badan, sida qalabka shaqada, udgoonka iyo molecules daroogada. Ketones caraf udgoon ayaa ah kuwa aad muhiim u ah dhismayaasha synthetic ee isku-dhafka dabiiciga ah, kuwaas oo si ballaaran uga jira qaababka asaasiga ah ee alaabta dabiiciga ah waxaana si ballaaran loo isticmaalaa xeryahooda firfircoon ee noolaha.

Iyadoo la ilaalinayo gaaska aan shaqaynayn, 2-methylphenylsulfonylhydrazide (1.1 mmol), benzonitrile (1.0 mmol), palladium catalyst (2 mol %) iyo biquinoline (bq, 3 mol %) ayaa lagu kala firdhiyey dareeraha organic (2 ml) ), ka dibna H2O (2 mmol) ayaa lagu daray, heerkulku wuxuu kor u kacay 80 ° C ilaa 6 saacadood. Kadibna xalka falcelinta ayaa la soo saaray saddex jeer Et2O (5 mL), wejiyada dabiiciga ah ayaa la isku daray, dareeraha ayaa lagu qallajiyey cadaadis yar. Badeecada cayriin ee la helay ayaa lagu sammeeyay chromatography tiirka on tiirarka silica jel (300-400 mesh), iyo eluents waxay ahaayeen petroleum ether, si loo helo badeecada la beegsanayo 2-methylbenzophenone. Waxyaabaha kiimikaad dareere hufan oo aan midab lahayn ama huruud ah. Heerkulka dhalaalka waa qiyaastii 134 ° C. U isticmaal sidii dhexdhexaad daawo ahaan.
