An efficient approach to access β-hydroxyhydrophosphonic acid derivatives is reported
by ring-opening reaction of readily available epoxides with green, inexpensive, and
safe inorganic salt sodium hypophosphate as the phosphorus source in the presence
of silver trifluoromethanesulfonate as the catalyst. The reaction is achieved under
simple operation and exhibits excellent selectivity as well as good functional group
compatibility.
