[B(OH)3]0.78[B(OH)2(OSO3H)]0.22 as a new, cheap and eco-friendly catalyst for synthesis of acylals at room temperature under solvent free conditions

چکیده مقاله

[B(OH)3]0.78[B(OH)2(OSO3H)]0.22 or (BSA) was simply prepared by addition of chlorosulfonic acid to commercial boric acid at room temperature. This cheap and green solid acid was used as an efficient catalyst for synthesis of acylals from aldehydes under solvent-free conditions at room temperature.
