In this study, solid acid magnetic nanoparticles Fe3O4@SiO2-S-Bu-SO3H were prepared under appropriate conditions and characterized by various analytical techniques including FT-IR, XRD, FE-SEM, EDX, VSM. Finally, the catalytic activity of synthesized MNPs was investigated for synthesis valuable benzothiazole derivatives condensation reaction ortho-aminothiophenol aldehydes ultrasonic conditions. presence inexpensive, environment-friendly, magnetically recoverable catalyst, benzothiazoles obtained as pure target products in excellent yields (90–98%) short times (3–11 min). The show great because combined effect Brønsted acidity high functional group density. This nanocatalyst is reusable several cycles can be easily segregated from mixture.
