Example 3. Hydroamination of Allenes and Alkynes with Ammonia[0085] General Catalytic Procedure: The catalyst (15 mg) and the appropriate amount of alkyne or allene (see main Figure 2 for mol %) were loaded into a Wilmad QPV thick walled (1.4 mm) NMR tube. C₆D₆ (0.4 mL) and benzyl methyl ether (5 mg) as an internal standard were added to the mixture. For low catalyst loading (0.1 mol%) experiments, 3 mg of catalyst and 0.1 mL of C₆D₆ were used. The NMR tube was connected to a high vacuum manifold and excess NH₃ (typically 3-6 equivalents) was carefully condensed at -60 ⁰C. For experiments with 1,2-propadiene, the allene was first condensed with subsequent addition of NH₃. The tube was sealed and placed into an oil bath behind a blast shield, and heated at the specified temperature. ChemDraw Ultra 10.0 was utilized to name most of the compounds presented in example 3.
