Reaction of α-Oxoketene Dithioacetals with Arylamines in the Presence of BF3-OEt2 for the Synthesis of Ketene S, N-Acetals

Reaction of α-Oxoketene Dithioacetals with Arylamines in the Presence of BF3-OEt2 for the Synthesis of Ketene S, N-Acetals

Reaction of α-oxoketene dithioacetals with arylamines was accelerated with a catalytic amount of BF3-OEt2 to give the corresponding α-oxoketene S, N-acetals selectively in good yields.
