化学性质
这是一种浅黄色的油状液体。其熔点为34-36℃,沸点在94.7kPa下约为285-286℃(轻微分解),而在0.8kPa下的沸点是163-164℃,相对密度为1.034(19/4℃),折光率为1.5930。它能够溶解于乙醇及其他有机溶剂,但不溶于水。
用途
该物质用作染料中间体,主要用于制造酸性淡绿SF以及其他蓝色染料。此外,还可以用于生产酸性橙50、红119、蓝5、7和绿5、15、65等染料的中间体。
生产方法
此化合物可由乙基苯胺与氯化苄反应制得。具体操作是在衬铅釜中加入乙基苯胺,边冷却边滴加氯化苄,搅拌10小时后在100℃下保温12小时。使用氢氧化钠溶液洗涤并经过真空蒸馏即可得到成品。另一种方法是以二乙基苯胺为原料,与氯化苄按摩尔比2:1混合,在150℃下加入1%的碘催化反应20小时后,再进行真空蒸馏获得产品。

A variety of acetamide derivatives are reduced in excellent yields to tertiary amines by PhMeSiH2 in the presence of Cp2TiX2 (X = F or Me) catalysts. The reactions are very clean at 80 °C. At room temperature a secondary reaction, hydrogenolysis of the C(O)N bond, intervenes and reduces the chemoselectivity. Nevertheless, this chemistry provides a simple methodology for the amide/alkylamine transformation using inexpensive, commercially available reagents.Key words: amides, reduction, secondary amides, methylphenylsilane, titanocene, catalysis.
