Applications & references

Suzuki-Miyaura coupling reactions of various substrates using a weak base showing the significant outperformance of Umicore CX231 compared to Umicore CX31. The conversion of substrates with deactivating electron-donating groups and substituents in the ortho-positions is feasible.
