Reaction Steps

Example 6 was repeated using 50 grams of 3-nitrophenylacetylene (19% wt. conc.) in isopropanol in the presence of 8.0 grams of said cobalt polysulfide catalyst (weight ratio of NPA to Co of 50:1) for 1.1 hours at 120° C. and 1000 psig (6.9 MPa) of hydrogen pressure. Analysis showed quantitative conversion and 82% yield of 3-aminophenylacetylene. All byproducts were polymeric. The results are summarized in Table 1 below.
