• The hydroformylation of butenes in nitrobenzene or nitroethane gives C<SUB>5</SUB>-aldehydes in an excellent yield in the presence of tetrarhodium dodecarbonyl, but in only a 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 C<SUB>4</SUB>-nitroaldehydes, mostly 2-methyl-3-nitropropionaldehyde, in a 96% yield. However, no reaction of nitroethylene occurred below 140°C.
