Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. HPLC of Formula: C8H12B2F8N4Pd. Introducing a new discovery about 21797-13-7, Name is Tetrakis(acetonitrile)palladium(II) tetrafluoroborate
Mono- versus dipalladation of the durene-based tetrathioether ligand 1,2,4,5-(tBuSCH2)4C6H2. Structures of [PdCl((tBuSCH2)4C6H)] and [Pd2((tBuSCH2)4C6)(MeCN) 2][BF4]2
Treatment of 1,2,4,5-(tBuSCH2)4C6H2 with K2PdCl4/NaOAc in ethanol yielded only the monopalladated complex [PdCl((tBuSCH2)4C6H)] regardless of whether 1 or 2 equiv of K2-PdCl4 is used. Alternately, the reaction of 1,2,4,5-(tBuSCH2)4C6H2 with 1 or 2 equiv of [Pd-(MeCN)4][BF4]2 in MeCN resulted in quantitative production of the dipalladated species [Pd2((tBuSCH2)4C6)(MeCN) 2][BF4]2 based on palladium starting material. The X-ray structures of the two products [PdCl((tBuSCH2)4C6H)] and [Pd2((tBuSCH2)4C6)(MeCN) 2][BF4]2 are reported. MO calculations were consistent with the idea that the ligand trans to the first Pd-C bond dictates the electrophilic aromatic substitution pattern and determines whether a second palladation will occur. Thus, Pd-Cl is deactivating while (Pd-MeCN)+ is activating, resulting in the formation of exclusively mono- and dipalladated products, respectively.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.HPLC of Formula: C8H12B2F8N4Pd, you can also check out more blogs about21797-13-7
