## Abstract Four trityl‐type (i.e. non‐substituted trityl‐, o‐Cl‐trityl‐, o‐F‐trityl‐ and p‐CN‐trityl‐) amidomethyl polystyrene resins were evaluated comparatively, in terms of the stability of the trityl‐ester bond in slightly acidic dichloromethane solutions, and the p‐CN‐trityl‐amidomethyl polys
Azidomethyl-polystyrene, obtained by nucleophilic substitution of chloromethyl-polystyrene, undergoes a Schmidt rearrangement when treated with trifluoromethanesulfonic acid, affording amino-polystyrene. To assess its loading and reactivity the resin is used as a support for the preparation of triaz
