The new hybrid NHC gold(I) acetonitrile polyoxometalate complexes {[Au(IPr)(MeCN)+][H+]3[SiW12O404−] (1), [Au(IPr)(MeCN)+][H+]2[PMo12O403−] (2), [Au(IPr)(MeCN)+][H+]5[P2W18O626−] (3), [Au(IPr)(MeCN)+][H+]2[PW12O403−] (4), [Au(IPr)(MeCN)+]3[PMo12O403−] (5) and [Au(ItBu)(MeCN)+] [H+]2[PMo12O403−] (6)} were readily synthesized in high yield and characterized by NMR and MS‐ESI spectroscopy. In a preliminary...
2-Carboxylated aza-rings have been synthesized in two steps through a highly selective monohalogenation of N-sulfonylated lactams of various ring sizes (from 5- to 8-membered rings) followed by a ring contraction reaction. The selective monohalogenation of N-sulfonyl lactams has been achieved in modest to excellent yields (9 examples, 39–96%) using N-halogenosuccinimides via the in situ generation...
