examples for the bromination, of readily available acrylamides to access a variety of differently substituted Z-haloacrylic acid derivatives is reported. The reaction proceeds under mild conditions via a Rh(III)-catalyzed C–H-activation/halogenation mechanism and represents a rare example of a direct halogenation of electron-poor acrylic acid derivatives.
