A versatile supported silver for heterogeneously catalysed processes: Synthesis of 3‐Acyloxylindolines solvent‐free conditions.

We have found that fibrous nanosilica (KCC‐1) can used as a excellent support for the synthesis of highly sparse nanoparticles and has high surface area that was functionalized with Tetrathia‐azacyclopentadecane (TTACP) groups acting as the strong performers so that the Ag nanoparticles were well‐dispersed without aggregation on the fibers of the KCC‐1 microspheres (KCC‐1/TTACP/Ag). We enthusiasm to report one‐pot synthesis of 3‐Acyloxylindolines for first time from <italic>N</italic>‐tosyl‐2‐vinylaniline, and benzoic acid in the presence of KCC‐1/TTACP/Ag as a catalyst.
