A novel polymer-supported imidazolium salt functionalized with t-alcohol (1) was prepared as a heterogeneous phase transfer catalyst (PTC) for several nucleophilic substitution reactions. The catalytic activity of 1 was validated in nucleophilic fluorination, comparing to polymer-supported triethylammonium salts and other imidazolium salts. By this comparison study, 1 has proved to show better performance, and it was reused up to several times without any loss of catalytic activity and product yield. In addition, 1 was successfully applied to other neculeophilic substitution reactions such as chlorination, bromination, acetoxylation, and azidation.
