我们在研究由二茂镍(Cp_2Ni)掺杂的蒽镁真空热解所得的活性镁加氢,脱氢动力学行为时,发现Cp_2Ni固体本身在氢气氛中,130℃就能够进行氢解反应。 1980年Каплин等报道了在流动的氢气气氛下,Cp_2Ni蒸气通过200—350℃反应管,得到加氢裂解产物,环戊二烯、环戊烯及环戊烷。当反应温度为200℃时,产物组成分布为环戊二烯1％,环戊烯68％, When we investigated the hydrogenation and dehydrogenation kinetics of activated magnesium obtained from the vacuum pyrolysis of anthracene and magnesium doped with Ni-Ni (Cp 2 Ni), we found that the hydrogenation of Cp 2 Ni solid itself can be carried out at 130 ℃ under hydrogen atmosphere. 1980 Каплин other reported in a flowing hydrogen atmosphere, Cp_2Ni vapor through the 200-350 ° C reaction tube to give hydrocracked products, cyclopentadiene, cyclopentene and cyclopentane. When the reaction temperature is 200 ℃, the product composition distribution of cyclopentadiene 1%, cyclopentene 68%
