Azide-ways manoeuver: Oxysulfonyl azide is developed for the formation of N-oxysulfonyl amidines. Three kinds of CuI catalysts are tested, which include CuI, Cu2I2(PDIN) without micropores, and Cu2I2(BTTP4) with micropores (PDIN=1,4-phenylene diisonicotinate, BTTP4=benzene-1,3,5-triyltriisonicotinate). Both homogeneous CuI and heterogeneous Cu2I2(BTTP4) are catalytically efficient and provide N-oxysulfonyl amidines in good yields.
