thiophene compounds with a Raney nickel was studied in ethanol at atmospheric pressure and from 0 to 78.3 °C. The desulfurization rate was initially fast but reached zero in about 30 minutes. The major products were biphenyl in the desulfurization of dibenzothiophene (1), 1-phenylnaphthalene in the desulfurization of benzo[b]naphtho[1,2-d]thiophene (2), and 2-phenylnaphthalene in the reaction of benzo[b]naphtho[2
在大气压和 0 至 78.3 °C 的乙醇中研究了多核噻吩化合物与雷尼镍的脱硫机理。脱硫速度最初很快,但在大约 30 分钟内达到零。主要产物为二苯并噻吩(1)脱硫中的联苯、苯并[b]萘并[1,2-d]噻吩(2)脱硫中的1-苯基萘和苯并[b]反应中的2-苯基萘萘并[2,3-d]噻吩(3)和苯并[b]萘并[2,1-d]噻吩(4)。四种化合物的脱硫程度依次为:3>1>2>4。多核噻吩化合物的脱硫程度与化合物硫原子的反应指数Fr(E)、Fr(N)和Fr(R)无关,这些反应指数是通过简单的Huckel计算得到的。理论; 相反,它与自由价和 π 电子密度有关。因此,多核噻吩化合物被认为吸附在雷尼镍通...
