4-chloro-3,5-dinitrobiphenyl → HCID 15180038, compound

Participants

Reaction Steps

A solution of 2.79 g. (0.01 mole) of 4-chloro-3,5-dinitrobiphenyl [R. C. Hall and C. S. Giam, J. Agr. Food Chem. 20 (3) 546-52 (1972) ] in 200 ml. of dioxane is hydrogenated at 3 atmospheres using Raney Nickel Catalyst. The catalyst is removed by filtration and the residue concentrated under reduced pressure. The residue is recrystallized from ethanol-water. There is obtained 1.12 g. (51%) of material melting at 142°-144.5°. Additional recrystallization raises the melting point to 146°-7°.
