Abstract
A novel surface tantalum methylidene [( SiO)Ta-V(=CH2)Cl-2] was obtained via thermal decomposition of the well-defined surface species [( SiO)(TaCl2Me2)-Cl-V]. This first surface tantalum methylidene ever synthesized has been fully characterized and the kinetics of the alpha-hydrogen abstraction reaction has also been investigated in the heterogeneous system.
