acetonitrile, primary and secondary nitriles, using alkylbromides and sodium amide in liquid ammonia. By reaction of the in situ formed organometallic Lewis acids [CpM(CO)(PPh3)](+) (M = Fe, Ru) with the novel tertiary nitriles, the complexes [CpM(CO)(PPh3)(NC C-(CRRR3)-R-1-R-2]BF4 were obtained. A di-iron complex was formed with 1,6-dicyanohexane.
在液氨中使用烷基溴和氨基钠,通过乙腈、伯腈和仲腈的烷基化合成了一系列叔腈。通过原位形成的有机金属路易斯酸 [CpM(CO)(PPh3)](+) (M = Fe, Ru) 与新型叔腈反应,复合物 [CpM(CO)(PPh3)(NC C-(得到CRRR3)-R-1-R-2]BF4,与1,6-二氰基己烷形成二铁络合物。
