) with aryl and alkyl acyl phosphonates, which lead to the formation of α-hydroxyphosphonates in moderate to good yields, are reported. This method provides easy access to secondary and tertiary α-hydroxyphosphonates depending on the reaction conditions. The reactions of triethylaluminum with a series of acyl phosphonates at 0 °C gave the secondary α-hydroxyphosphonates, while at −100 °C they afford
