Reaction of alcohols with dialkyl phosphites in the presence of titanium tetraalkoxides results in a displacement of both or one ester function(s) by the RO groups of the alcohol used. The mixed phosphites, (R3O)(R1O)P(O)H, prepared by this method can be used as substrates for the mixed phosphates, (R4O)(R3O)(R1O)PO.
