Daim Ntawv Thov

Nyob rau hauv kev tiv thaiv ntawm cov roj inert, 2-methylphenylsulfonylhydrazide (1.1 mmol), benzonitrile (1.0 mmol), palladium catalyst (2 mol%) thiab biquinoline (bq, 3 mol%) tau tawg ua cov organic solvent (2 mL) ), tom qab ntawd H2O (2 mmol) tau ntxiv, thiab qhov kub tau tsa mus rau 80 ° C rau 6 teev. Tom qab ntawd cov tshuaj tiv thaiv tau rho tawm peb zaug nrog Et2O (5 mL), cov theem organic tau sib xyaw ua ke, thiab cov kuab tshuaj tau spin-dried nyob rau hauv qhov txo qis siab. Cov khoom nyoos tau txais tau raug rau kem chromatography ntawm kem silica gel (300-400 mesh), thiab cov eluents yog roj av ether, kom tau txais cov khoom lag luam 2-methylbenzophenone. Cov khoom siv tshuaj lom neeg Tsis muaj xim lossis daj daj pob tshab kua. Lub ntsiab lus yaj yog li 134 ° C. Siv ua tshuaj nruab nrab.
