Hybrid catalysts A and B have recently been found to efficiently transfer electrons from a metal catalyst to molecular oxygen in biomimetic oxidations. In the present work hybrid catalysts A and B were synthesized in high yield from inexpensive starting materials. The key step is an efficient Suzuki cross‐coupling, which allows the use of unprotected aldehyde 5 . The new synthesis of the title hybrid catalysts is easy to carry out and can be scaled up.
