A green and efficient method has been accomplished for the synthesis of α-hydroxyphosphonates using silica-supported tungstic acid (STA) as a heterogeneous catalyst under solvent-free conditions at ambient temperature. The compounds obtained were characterized by spectral and analytical studies and...
