A novel gold (I)-catalyzed synthetic strategy has been achieved for an efficient construction of indenylidene derivatives from substituted 1,6-diynes. This reaction describes the unique reactivity catalysis in facilitating intramolecular [3,3]-sigmatropic rearrangement, 5-exo dig cyclization followed by 1,5-migration acryl group, resulting formation indenylidenes. Various indenylidenes were successfully synthesized with up to 92 % yields. In this protocol, two new C-C bonds sequentially formed atom economically one pot.

Silver-catalyzed N-aryl-1H-pyrazolyl substituted benzenesulfonamide derivatives were obtained regioselectively from ynamides and pyrazoles. In this intermolecular organic transformation, several benzenesulfonamides in good to excellent yields by forming a new C-N bond under mild reaction conditions.
