甲碘化物

The effects of above-mentionedconditions on alkylene reaction are studied to obtain the optimum reactive conditionsby orthogonal experiments having seven factors and three levels. GCLE is chosen as material to prepare 7-phenyl acetamideyl vinyl cephalkyl acidp-methoxy benyl eatsr in the experiment. The process is as follow: GCLE reacts withiodide in solvent, and produce 3-iodid, then reacts with PPh_3 to produce Witting agent,and reacts with HCHO to produce 7-phenyl acetamideyl vinyl cephalkyl acid p-methoxy benyl eatsr in alkaline conditions.

试验选用GCLE作为原料制备7-苯乙酰氨基-3-乙烯基头孢烷酸对甲氧苄酯，反应过程如下：GCLE与碘化物、PPh3在溶剂中反应生成3位膦盐，在碱性条件下生成Wittig试剂再与HCHO反应生成7-苯乙酰氨基-3-乙烯基头孢烷酸对甲氧苄酯。

Experimental process: jing and 3- methyl -2- methyl ethyl ketonesynthesizes by the benzene zong; Again the glacial acetic acidcatalysis produces 2, 3, 3 - trimethyl - 3H - yinduo; Again has thealkylate response production yinduo iodide after the methyl iodide;The iodide takes off molecular HI under NaOH to become freejier thealkali; Adds 5 - nitryls salicylic aldehydes in the ethyl alcohol forthe solvent under if to respond finally produces 6 '- the nitryl yinduolin spiral benzene and pinan; Through the infrared spectrum andthe ultimate analysis irrevocably proved its structure, and studiedthe annulus with to open the annulus the light to send changes colorthe performance, explained in different solvent medium ultravioletabsorption spectrometry solvent effect, and the comparisondiscoloration the response speed number difference, finally mixed itadds to the methyl methacrylate, the peroxidation benzoin formyl in the plexiglass, tested 6 '- the nitryl yinduolin spiralbenzene and pinan in the glass fatigue resistance, thethermostability.

实验过程：由苯肼和3-甲基-2-丁酮合成腙；再冰醋酸催化生成2 ，3 ，3—三甲基—3H—吲哚；再经过碘甲烷发生烷基化反应生成吲哚碘化物；碘化物在NaOH下脱去一分子HI成为费歇尔碱；在乙醇为溶剂下加5－硝基水杨醛与其反应最后生成6'—硝基吲哚啉螺苯并吡喃；通过红外光谱和元素分析确证其结构，并研究了环体与开环体的光致变色性能，解释了在不同溶剂介质中紫外吸收光谱的溶剂效应，并比较褪色反应速率数的差异，最后将其掺加到甲基丙烯酸甲酯，过氧化二苯甲酰有机玻璃中，测试6'—硝基吲哚啉螺苯并吡喃在玻璃中的抗疲劳性、热稳定性。
