Homework Help: General organic reaction question

  1. May 26, 2007 #1
    I have here an alkyne reacting with C2H5NH2 in the presence of lithium and NH4Cl.

    Does the lithium catalyse the split of a proton from C2H5NH2 and also a Cl from the NH4Cl which then react with the alkyne across the triple bond?

    It looks like a two step reaction. First step is lithium + ethylamine in the presence of your alkyne. Can you determine the reaction products between lithium metal and ethylamine? Can one or more of those products react with the alkyne?

    Ammonium chloride is used to quench the reaction and work up the product.
