本文研究了環(huán)己酮和丙二腈與硫磺反應(yīng)制得a，產(chǎn)率91.01%，反應(yīng)產(chǎn)物與三氟乙酸和三氯氧磷反應(yīng)制得b，產(chǎn)率為x,b再與c的衍生物反應(yīng)制得d的衍生物，產(chǎn)率為20%~30%。目標(biāo)化合物的結(jié)構(gòu)經(jīng)紅外光譜、核磁共振氫譜與質(zhì)譜表征。同時(shí)對(duì)目標(biāo)化合物的合成方法以及合成條件也進(jìn)行了探討。關(guān)鍵詞：含氟、溴衍生物；合成 十分感謝！急呀，在寫(xiě)論文  |

Preparation of compound a in 91.01% yield with cyclohexanone, malonic nitrile and sulfur was studied in this paper. The product a reacted with trifluroacetic acid and trichlorophosphine oxide to afford b in x% yield, and b further reacted with derivative of c to give derivative of d in 20%~30% yield. Structure of the target product was characterized by IR, NMR and MS. Synthetic methods as well as conditions for the target product were also researched. Keywords: Fluoro and bromo derivatives; synthesis |
