Interaction of BF3 NH2C2H5 with DDS and TGDDM

19F NMR studies, illustrated in Table 4, indicate that the TGDDM epoxide enhances BF4 salt formation in DMSO solution. For example, after exposure to 115 °C for 1 h, all the BF3 NH2C2HS species have disappeared in the presence of TGDDM. However, in DMSO solution in the absence of TGDDM, 50% of the total fluorine species are still in the form of BF3 NH2C2H5 after 1 h exposure at 115 °C (Table 3).
