Herein, we report an efficient one-pot iridium-catalyzed reductive hydroamination of terminalalkynes with amines. A variety of primary amines and secondary amines are amenable to this catalytic system, leading to the complicated aliphatic amines in excellent yields. More broadly, this straightforward and convenient transformation do not just employ inexpensive and easy to handle HCO2H as reducing
friendly method for the direct amination of secondary benzyl alcohols with amides or 4-nitroaniline is described. This method has been applied to a variety of substrates, and the reaction proceeded smoothly at room temperature under solvent-free conditions. CbzNH2 was proved to be very useful in the direct preparation of the benzylic amines from corresponding alcohols.
