An efficient regioselective synthesis of 2-acylpyrroles via palladium-catalyzed addition of pyrroles with benzonitriles and subsequent hydrolysis is developed. The direct acylation reaction of protected as well as (NH)-free pyrroles proceeded smoothly to

Zn(OTf)2·6H2O was used to promote Friedel-Crafts acylation of aromatics. The work describes the high activity and efficiency of Zn(OTf)2·6H2O in acylation of aromatics, and the catalyst has surpassed most metal triflates in dispensing when dried at high temperature under vacuum before use.

Ytterbium (III) trifluoromethanesulfonate catalysed Friedel-Crafts acylation of 1-methylpyrrole in ionic liquid
Su, Weike,Wu, Chunlei,Su, Hao
, p. 67 - 68 (2007/10/03)
In the presence of a catalytic amount of ytterbium (III) trifluoromethanesulfonate [Yb(OTf)3], 1-methylpyrrole can easily react with acyl chlorides in an ionic liquid [bpy][BF4](bpy=1- butylpyridine) to form corresponding ketones in satisfactory yield. The recyclability of the ionic liquid/catalyst system is demonstrated.
