Abstract: I have discovered a process for making nitroarylacetylenes and aminoarylacetylenes in which the aryl radical is a phenylene radical or a diphenylene radical. With the exception of p-aminophenylacetylene, the compounds produced by this process are novel. The compounds are all useful as intermediates in the preparation of addition polymers utilizing a polymeric backbone of polyimides. The addition polymers are useful as adhesives and as laminating resins.
