WebThe first transition-metal-free regioselective synthesis of 2,3-diarylindenones via tandem annulation of 2-alkynylbenzaldehydes with phenols is described. Two different modes of reaction controlled by electronic effects and temperature furnished either “non-rearranged” or “rearranged” indenones in high selectivity. WebDec 30, 2024 · N, N’ -Diarylated dihydroazaacenes, 1, 2, and 3, were synthesized through Buchwald-Hartwig amination of aryl iodides with N, N’ -dihydroazaacenes. Upon monooxidation of the neutral compounds, the radical cations 1+., 2+., and 3+. formed, stable in DCM under ambient conditions for at least 24 h.
