Tomislav Rovisdoi:10.1246/cl.2008.2
The development of a family of chiral bicyclic triazolium salts is described. Treatment of these salts with base provides anucleophilic carbene which may be used as an organic catalyst for asymmetric acyl anion chemistry including the benzoinand Stetter reactions, and some recently developed redox chemistry. Throughout the development of these reactions, thenature of the N-aryl substituent on the triazole ring has proven to have a profound effect on both reactivity and selectivity.These observations have also paralleled those made by others using our family of catalysts.

120 Mixed-potential-type Zirconia-based SensorUsing In2O3 Sensing-Electrode for SelectiveDetection of Methane at High Temperature
A mixed-potential-type yttria-stabilizedzirconia (YSZ)-based sensor using In2O3
sensing electrode (SE) showed the highsensitivity as well as good selectivity toCH4 at 790 °C. The senor attached withthe 1300 °C-sintered In2O3-SE showedquicker response which was aboutfifteen times higher than that for the1400 °C-sintered In2O3-SE. -120
