2-Fluorobenzonitrile
C7H4FN
CAS Nr.: 394-47-8
Daim ntawv thov
Txoj kev npaj: Sau lub microwave reactor nrog 6.88g (50 mmol) ntawm o-chlorobenzonitrile, 11.6g (200 mmol) KF, 20 ml ntawm sulfolane, thiab 2.1 g (5 mmol) ntawm tetraphenylphosphonium bromide nyob rau hauv qhov kev txiav txim. Ua kom sov lub reactor nrog 300 W ntawm lub hwj chim, ces siv GC ua raws li cov tshuaj tiv thaiv Chemicalbook. Cov tshuaj tiv thaiv xaus thaum cov khoom siv raw cov ntsiab lus tsawg dua 5%. Tom qab plaub teev ntawm cov tshuaj tiv thaiv ntawm 180 degree, lub microwave nres cov tshuaj tiv thaiv. Tom qab cov tshuaj tiv thaiv raug coj mus rau hauv chav tsev kub, lub tshuab nqus tsev lim yog siv los tshem tawm cov khoom insoluble. 2-fluorobenzonitrile yog qhov tshwm sim ntawm distilling lub filtrate ntawm qis dua. Qhov kawg tawm los ntawm 74.6% ntawm 4.56g.
