Propanephosphonic anhydride

Propanephosphonic anhydride (440) has been demonstrated to be an efficient activator for the chemoselective acetalisation and thioacetali-sation of aldehydes in the presence of ketones. Thus, cyclic and acyclic acetals (443) and thioacetals (444) were obtained in excellent yields (89-96%) at room temperature in the presence of a catal)ffic amount of (440) (Scheme 152). ... [Pg.319]
