                                Catalytic aminomercuration reactions of 3-alken-1-ynes: an improved method for the synthesis of 2-amino-1,3-butadienes and 1-aza-1,3-butadienes
                             
                            
                                摘要:
                                Catalytic aminomercuration of 3-alken-1-ynes leads to 1-aza-1,3-butadienes and 2-amino-1,3-butadienes.  Under appropriate reaction conditions it is possible to prepare these compounds via mercuration of 3-alken-1-ynes in the presence of either aromatic or aliphatic primary and secondary amines.  Depending on the substituents in the starting 3-alken-1-yne, the mercuration reaction may afford gamma-amino enamines instead of 2-amino-1,3-butadienes and 3-imino amines or 4-amino-1-aza-1,3-butadienes instead of 1-aza-1,3-butadienes.
