Synthesis of Dialkyl 2,3-Alkadienephosphonates by Reaction of the 1-Copper(I) Derivatives of Alkyl Alkanephosphonates with 2-Alkynyl Halides, 2-Alkynyl Benzenesulfonates, or 1-Bromoallenes
A method for producing a propargylamine compound represented by the general formula (I):
which comprises reacting a propargyl compound represented by the general formula (II):
with an aromatic aldehyde represented by the general formula (III):
ArCHO (III)
and ammonia to obtain an imine compound represented by the general formula (IV):
and hydrolyzing the resultant imine compound. It is to provide a method for producing a propargylamine compound from a propargyl compound by a simple operation without using a special facility, using ammonia as a reaction reagent, without producing a dipropatygylamine compound and a tripropargylamine compound as by-products.
