The Effect of the C5-Substituent on Regioselectivity in the Rh(I)-Catalyzed Intermolecular Transannulation of 1,2,3-Thiadiazoles with Phenylacetylene Marina A. Tokareva, Indrek Pernik, Barbara Messerle, Tatiana V. Glukhareva and Sinead Keaveney Abstract Despite the growing use of denitrogenative reactions of 1,2,3-thiadiazoles in heterocycle synthesis, the origin of the varied reactivity and divergent regioselectivity observed in their transannulation reactions is not well understood.

Carbon Supported Hybrid Catalysts for Controlled Product Selectivity in the Hydrosilylation of Alkynes Max Roemer, Vinicius Romero Gonçales, Sinead Teresa Keaveney, Indrek Pernik, Jiaxin Lian, James Downes, John Justin Gooding and Barbara Messerle Abstract A series of Rh- and Ir-hybrid catalysts with varying tether lengths has been prepared by immobilization of RhI, RhIII and IrIII complexes on carbon black via radical grafting.
