Homogeneous catalysts grafted onto carbon nanotubes that are magnetic

What is it about?

We prepared carbon nanotubes decorated of filled with iron oxide nanoparticles to make them magnetically recoverable. Using xanthate chemistry, we then grafted a typical C-C coupling homogeneous catalyst consisting of Pd(II) centers. Therefore, the organometallic catalyst becomes supported on a solid and can be recycled by the simple use of a magnet.

Why is it important?

Organometallic catalysts are typically very active and selective but very difficult to recover. Here we propose a simple strategy to obtain single-site active catalysts grafted on a magnetic support. Hence the molecular catalyst can be isolated with a simple magnet and reused.
