[(SiO)TaV(CH2)Cl2], the first tantalum methylidene species prepared and identified on the silica surface

• A novel surface tantalum methylidene [(SiO)TaV(CH2)Cl2] was obtained via thermal decomposition of a well-defined surface species [(SiO)TaVCl2Me2].
• It is the first fully characterized surface tantalum methylidene compound.
• The kinetics of the α-hydrogen abstraction reaction has been investigated, which supported a monomolecular α-H hydrogen abstraction mechanism.
• We highlighted surface organometallic species is an effective tool to study some transformation which would not be observable in a homogeneous system.

This first surface tantalum methylidene ever synthesized has been fully characterized and the kinetics of the α-hydrogen abstraction reaction has also been investigated in the heterogeneous system.
