Abstract In this investigation, a novel magnetic phosphoniumionicliquid (MPIL) was designed and synthesized through a two-step process. The resulting magnetic ionicliquid was fully characterized using different techniques including Fourier-transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), derivative thermogravimetric analysis (DTG), energy-dispersive X-ray spectroscopy (EDX)

AgI nanoparticles were discovered to be an effectual heterogeneous nanocatalyst for the preparation of (amidoalkyl)naphthol and oxazine derivatives under solvent-free conditions. The advantages of the present approach are short reaction times, moderate temperature, premier yields, eco-friendly reaction conditions, simple purification and good reusability of the catalyst.

solvent-free conditions is explained. The prepared amidoalkyl naphthols were converted to 1,3-oxazines by Vilsmeier reagent in the presence of FeCl3/SiO2 nanoparticles. This method provides a novel route to synthesis amidoalkyl naphthol and 1,3-oxazine derivatives in terms of good yields, short reaction times, and recyclable catalyst. Graphical abstract
