represent 98% of products formed, with 2% of the reaction mixture containing at least up to seven unidentified products, while with benzyl magnesium bromide (1b), the three main products 2b, 3b and 4b represent 80% of the reaction mixture, the remaining 20% containing up to nine products with benzyl bromide being the main side product. The complexity of the reaction increases even more in the case of phenyl
在室温下,几种乙醚溶液中的格氏试剂容易与二氟化氙反应,反应过程的复杂程度取决于试剂的结构。在所有研究的案例中,都形成了三种主要类型的产物,即1-乙氧基-1-取代的乙烷(2),还原产物(3)和二聚产物(4)。在十二烷基溴化镁(1a)的情况下,形成的2-乙氧基十二烷(2a),癸烷(3a)和二十烷(4a)代表98%的生成产物,其中2%的反应混合物至少包含七个未鉴定的产物,而在苄基溴化镁(1b)中,三种主要产物2b,3b和4b占反应混合物的80%,其余20%最多包含9种产物,而苄基溴是主要副产物。
