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 N‐tosyl‐2‐vinylaniline, and benzoic acid in the presence of KCC‐1/TTACP/Ag as a catalyst. 相似文献

Novel heterogeneous catalyst systems comprised of a fibrous nanosilica‐supported nano‐Ni@Pd‐based ionic liquid (KCC‐1/IL/Ni@Pd) are described for the cyclization of propargylic amines with CO2 to provide 2‐oxazolidinones. KCC‐1 with high surface area was functionalized with IL acting as a robust anchor so that the nano‐Ni@Pd was well dispersed on the fibres of the KCC‐1 microspheres, without aggregation. Because of the amplification effect of IL, high loading capacities of the nanocatalysts were achieved. The reported synthesis includes several advantages like solvent‐free conditions, operational simplicity, short reaction times, environmentally benign reaction conditions, cost effectiveness, high atom economy and excellent yields, making it a genuinely green protocol. 相似文献
