Treatment of α,α-dialkyl triethyl β-phosphonyl esters with LiAlH 4 in CH 2 Cl 2 –THF caused the one-pot dephosphonylation and reduction to yield the corresponding primary alcohols bearing a controllable β secondary carbon center. Mechanisticstudy has revealed that the LiAlH 4 -induced dephosphonylation should occur first with the assistance of the carboxylate group, and the hydrogen source of the
