In recent years, clean and sustainable mechanochem. solvent-free reactions have emerged as a viable alternative to solution chem. In order to completely solve the problem of environmental pollution caused by solvents and surfactants in LASC and LASSC systems, a green method for the in situ preparation of environmentally friendly inorganic polymeric Lewis acids and silica gel as nanocatalysts (PLASC) under solvent-free mech. grinding conditions was designed and realized by mechanochem. means, which is simple to operate and the process generates no other waste. Subsequently, 3-alkylindole derivatives (35-75%), β-amino alc. derivatives (90%), benzimidazole derivatives (85-90%) and quinoxaline derivatives (93-99%) were synthesized by a one-pot cooking method under continuous grinding conditions.

The true active center -O-Fe-O-Si-O-/-O-Si-O-Al-O- chem. bonding unit was revealed and found to be a nanoscale fibrous structure that is highly stable and can be reused at least 10 times without deactivation. The PLASC catalyst has remarkable green chem. properties such as easy recycling and a very low E factor, making it a new type of cheap, efficient and green catalyst.
