Cov ntawv thov tseem ceeb
18-Crown-6 yog siv los ua cov txheej txheem hloov pauv hloov pauv tau zoo thiab ua tus neeg sawv cev nyuaj nrog ntau yam me me cation. Nws koom nrog hauv kev sib txuas ntawm diaryl ethers, diaryl thioethers, thiab diarylamines kho los ntawm potassium fluoride-alumina thiab 18-crown-6. Nws txhawb kev solubility ntawm poov tshuaj permanganate hauv benzene, uas yog siv rau oxidizing cov organic tebchaw. Nws yog siv los ua kom muaj ntau yam kev hloov pauv thiab txhim kho lub zog ntawm nucleophiles xws li potassium acetate. Nws yog siv nyob rau hauv cov tshuaj tiv thaiv alkylation nyob rau hauv muaj cov poov tshuaj carbonate, N-alkylation ntawm glutarimide thiab succinimide nrog dimethylcarbonate. Lub complex tsim los ntawm nws cov tshuaj tiv thaiv nrog poov tshuaj cyanide ua raws li ib tug catalyst nyob rau hauv lub cyanosilylation ntawm aldehydes, ketones thiab quinines nrog trimethylsilyl cyanide (TMSCN).
