In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 21797-13-7, name is Tetrakis(acetonitrile)palladium(II) tetrafluoroborate, introducing its new discovery.

Phenolic compounds can be prepared by catalytic decarboxylation of 4-hydroxybenzoic acid or desulfonation of 4-hydorxybenzene sulfonic acid. Palladium complexes are shown to be highly active in the decarboxylation reaction, but complexes of platinum or ruthenium also show some activity in this reaction. Highly electron donating diphosphines such as BDTBPMB or monophosphines such as PtBu3 were found to be more effective than the less donating dppe or PPh3. The addition of D 2O led to deuteration of the aromatic ring mainly in the position ortho to the hydroxyl group. Phenol can also be generated by SO3 extrusion from 4-hydroxybenzenesulfonic acid catalysed by highly electron rich palladium complexes. The Royal Society of Chemistry 2009.
We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 21797-13-7, and how the biochemistry of the body works.Safety of Tetrakis(acetonitrile)palladium(II) tetrafluoroborate
