Abstract
A series of twenty halomethylated β-enaminones [RC(O)CH=C(R1)NR3R4, where R = CF3,CCl3, CHCl2; R1 = H, Me, Ph; R3 = H, Me, Bu, Et; R4 = Me, Et, Bu, allyl, tert-amyl, CH2CH2OH, Bn, Ph] were synthesized using the ionic liquid [bmim]BF4 at room temperature. It is demonstrated that this ionic liquid is a reaction medium suitable for the amination of β-alkoxyvinyl halomethyl ketones. The advantages of this method are the absence of solvents, short reaction times, and good yields.
