poor yield in the presence of dicobalt octacarbonyl. Under hydroformylation conditions, nitrobenzene is hydrogenated to aniline above 150°C with rhodium carbonyl and at 125°C with cobalt carbonyl. The hydroformylation of nitroalkenes with rhodium carbonyl is described. 4-Nitrostyrene gives isomeric (4-nitrophenyl)-propionaldehydes in a 96% yield. 3-Nitropropene-1 gives C4-nitroaldehydes, mostly 2-
丁烯在硝基苯或硝基乙烷中的加氢甲酰化在十二羰基四铑存在下以极好的收率得到 C5-醛,但在八羰基二钴存在下收率很低。在加氢甲酰化条件下,硝基苯在 150°C 以上用羰基铑和 125°C 用羰基钴氢化成苯胺。描述了硝基烯烃与羰基铑的加氢甲酰化。4-硝基苯乙烯以 96% 的产率得到异构的 (4-硝基苯基)-丙醛。3-Nitropropene-1 生成 C4-硝基醛,主要是 2-methyl-3-nitropropionalaldehyde,产率为 96%。然而,硝基乙烯在低于 140°C 时不发生反应。
