ABSTRACT:
Aromatic nitroacetylene compounds wherein both the nitro and acetylene groups are directly connected to aromatic ring carbon atoms are hydrogenated in dilute concentration in an inert solvent at high conversion levels to selectively reduce the nitro function using an unsupported ruthenium disulfide catalyst. Of particular interest is the preparation of an aminophenylacetylene from a nitrophenylacetylene.
