Having identified optimal reaction conditions, we set out to explore the generality of the amidyl radical insertion reaction to BCBs. First, we evaluated the scope of BCBs 1 by using N-amidocollidinium tetrafluoroborate 2d as an amidyl radical source (Fig. ). Different electron-withdrawing and donating groups at para-, meta-, and ortho-position on the aromatic ring of BCB such as fluoro-, trifluoromethyl-, trifluoromethoxy-, bromo-, methyl-, and methoxy-proved to be compatible affording the desired products 3b-3j in moderate to good yields (52-72%). Additionally, BCBs with different functional groups such as benzyl ester, allyl ester, N-methoxy-N-methyl amide, and phenyl ketone reacted well to offer corresponding products 3k-3n in 48-67% yields, respectively.
