In this paper, a diimine palladium complex with suitable steric hindrance of isopropyl groups and electron supply provides excellent protection for palladium active centers was synthesized and anchored on graphene oxide (GO) to obtain a reusable heterogeneous catalyst (Pd-DI@GO). The XPS results confirmed the effective loading of palladium and the interaction between palladium and ligand. The ICP-AES data verified the Pd content of catalyst was 5.04 wt% and confirmed extremely small amount Pd leaching in Suzuki reaction (<1 ppm). The Pd-DI@GO can catalyze Suzuki reaction under milder conditions and afford 39 reactants with high yields (79%?99%). It can achieve a yield as high as 99% with heterocyclic compound reactants which can poison the catalyst. The yields of double and triple substitutions are also impressive (70?92%). The Pd-DI@GO can catalyze the C?H direct arylation reaction efficiently, affording 22 reactants with superior yields (>85%). Notably, the Pd-DI@GO can be recycled after Suzuki reaction via filtration or centrifugation easily, presenting a yield above 90% for the 4th run.

In an article，Which mentioned a new discovery about 1532-97-4

The palladium-tetraphosphine catalyzed arylation of an alkylidenecyclopropane gives a simple and direct access to 1-aryl-2-methyl-1-(2,2,3,3-tetramethylcyclopropylidene)propenes. This reaction tolerates several functional groups on the aryl bromides. Even heteroaryl bromides have been used successfully. This reaction probably proceeds via a classical oxidative addition of the aryl bromide to palladium, insertion of the C{double bond, long}CMe2 bond in the Ar-Pd bond followed by beta-elimination to give the dienes.
