WebJun 1, 2024 · The apparent activation energies (E a) of the BCB monomers were in the range of 129.1–137.9 J/g, which are slightly lower than that of unsubstituted BCB in literature [27], [28], [39], as a result of the presence of electron-donating methylene group on the four-membered ring. Webbond relevant to BCB formation, leaving intact the iodide found in BCB 2b, which was isolated in a good yield of 70%. The products 2a, 2c, and 2g are isolated in high yields, above 80%. Surprisingly, the 4-fluoro substituted product 2d has a lower yield at 53%, while the yield improved for fluorine-containing 2e (65%) and 2g (85%). The selective
