A phosphine-mediated synthesis of trifluoromethyl substituted pyrrole derivatives was achieved. The method described here is very fast, operationally simple, and easily amenable to scale-up, and commercially available trifluoroacetic anhydride (TFAA) is used as the only trifluoromethyl source. A wide range of products were obtained with good yields under mild condition using this method. 0(C)2014 Elsevier Ltd. All rights reserved.
