Seed- and solvent-free synthesis of MFI zeolites with tuneable Si/Al ratios (18-∞) was achieved. The key role of F− was evidenced that forming 6-coordinated “F–Al–O–Si” species drove the formation of the zeolitic framework during crystallization.

AbstractA solvent-free microwave-assisted method for the synthesis of 2-substituted-4,5-di(2-furyl)-1H-imidazoles was developed. Imidazoles with moderate to good yields were produced by condensation of furil with aldehydes over acidic alumina impregnated with ammonium acetate, and they were characterized by FT-IR, HRMS,
