A picture of (non)innocence: Non-innocent and bulky phosphanes bearing a reducing cycloheptatrienyl–cyclopentadienyl titanium moiety swiftly convert PdII into Pd0 species at room temperature (see scheme). The resulting complex catalyzes the Suzuki–Miyaura coupling with fast conversion even of sterically hindered aryl bromides.
