ABSTRACT:
Aromatic nitroacetylene compounds wherein both the nitro and acetylene groups are directly connected to aromatic ring carbon atoms are hydrogenated at high conversion levels to selectively reduce the nitro function using an unsupported cobalt polysulfide catalyst. Of particular interest is the preparation of aminophenylacetylenes from nitrophenylacetylene.
