The kinetic parameters for the condensation of benzaldehyde with 3,3-bis-(chloromethyl)oxacyclobutane have been determined. It has been established by competition methods that aliphatic and p-substituted (Br, OCH3, OC2H5) aromatic aldehydes are more reactive than benzaldehyde. The proposed rate-determining step involves nucleophilic attack on a hydroxyalkyl (aryl) carbonium ion. |
