A process for preparing a 2-aralkyl-5,5-dialkyl-1,3,2-dioxaphosphorinan-2-one by heating a 2-aralkyloxy-5,5-dialkyl-1,3,2-dioxaphosphorinane such as the novel 2-benzyloxy-5,5-dimethyl-1,3,2-dioxaphosphorinane, with a catalytic quantity of an aralkyl halide. The aralkyl halide can be recovered and recycled. |
