      Isolated TaIII and TaV hydride centres [(≡SiO)2TaH] and [(≡SiO)2TaH3] supported on a silica surface cleave N2 with H2 at 250 °C and atmospheric pressure and activate NH3 at room temperature to yield the TaV amido imido product [(≡SiO)2Ta(=NH)(NH2)]. Their synthesis by surface organometallic chemistry (SOMC), reactivity toward C–H and C–C bonds of alkanes and this new reactivity toward the N≡N and N–H bonds are reviewed from a mechanistic point of view.
