Cyclic phosphorochloridates and phenylphosphonates based on the 1,3,2-dioxaphospholane and 1,3,2-dioxaphosphorinane ring systems, undergo ring cleavage when treated with phenylmagnesium halides to yield ω-hydroxyalkyl diphenylphosphinic acid is a major product of the reaction. Possible mechanisms for these reactions are discussed.
