In heterogeneous catalysis, the catalyst is in a different phase from the reactants. category: catalyst-palladium, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 21797-13-7, name is Tetrakis(acetonitrile)palladium(II) tetrafluoroborate. In an article，Which mentioned a new discovery about 21797-13-7
Reaction of the functionalised thioether crowns [14]aneS4-6-one (1,4,8,11-tetrathiacyclotetradecan-6-one, L1) and [10]aneS3-9-one (1,4,7-trithiacyclodecan-9-one, L2) with 2,4-dinitrophenylhydrazine in a protic solvent under acidic catalysis afforded the corresponding hydrazones L3 and L4, respectively, in high yield. Reaction of [14]aneS4-6-one with p-nitrophenylhydrazine under similar conditions affords the hydrazone L5. Reaction of L3 with [Pd(MeCN)4][BF4]2 in MeCN yielded the complex [Pd(L3)][BF4]2, while reaction of this ligand with [Pt(EtCN)4][CF3SO3]2 in MeCN afforded [Pt(L3)][CF3SO3]2. The single-crystal structures of L3-L5 and of [Pd(L3)][BF4]2 have been determined. In all cases, pi-pi stacking is observed, the free macrocycles crystallising as polymeric arrays of face-sharing hydrazone moieties. In [Pd(L3)]2+, pi-pi interactions alternate with face sharing between planar [PdS4]2+ units constructing a one-dimensional polymeric array. The hydrazone function forces distortions of the respective macrocyclic rings and imparts chirality to the [Pd(L3)]2+ cation. The potential of these molecules as building blocks for macrocyclic liquid crystals and extended supramolecular arrays is discussed, as is the need to consider steric factors in rationalising the reactivity of keto-functionalised thioether crowns.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 21797-13-7, help many people in the next few years.category: catalyst-palladium
