The reactions of 2-ethyl- and 2-n-propyl-2-(chloromethyl)-1,3-dichloropropanes with magnesium in tetrahydrofuran were investigated. Hydrolysis of these Grignard reagents produced 2-ethyl-1-butene and 2-ethyl-1-pentene as the major product in the respective cases; carboxylation of the same organomagnesium compounds gave 4-ethyl- and 4-n-propyl-4-pentenoic acid, respectively. These products were consistent
研究了2-乙基和2-正丙基-2-(氯甲基)-1,3-二氯丙烷与镁在四氢呋喃中的反应。这些格氏试剂的水解分别产生2-乙基-1-丁烯和2-乙基-1-戊烯作为主要产物。相同的有机镁化合物的羧化分别得到4-乙基-和4-正丙基-4-戊烯酸。这些产物与以下假设相符:反应通过烷基氯甲基环丙烷的形成和重排进行,如先前针对甲基同系物报道的1。通过常规分析和交替合成均可确定拟议化合物的身份。
