Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. COA of Formula: C8H12B2F8N4Pd. Introducing a new discovery about 21797-13-7, Name is Tetrakis(acetonitrile)palladium(II) tetrafluoroborate
A series of new complexes have been synthesized from reactions of [M(NCCH3)4][BF4]2 (M = Pd, Pt) with the mixed donor ligand tris(2,4,6-trimethoxyphenyl) phosphine (TMPP). Reaction of [Pd(NCCH3)4][BF4]2 with two equivalents of TMPP in acetone produces the ether-phosphine complex [Pd(TMPP)2][BF4]2, 1. In this molecule the Pd atom is situated at the center of a pseudo-octahedron, with the phosphorus atoms in a cis orientation. The complex was also characterized by infrared, electronic, and NMR spectroscopies as well as by cyclic voltammetry. Reaction of [Pd(NCCH3)4][BF4]2 with four equivalents of TMPP in acetone yields the neutral phosphino-phenoxide compound Pd(TMPP-O)2, 2, where TMPP-O is the demethylated form of TMPP. 1H and 31P{1H} NMR studies of 2 support the assignment of a solution structure that involves free rotation of the uncoordinated phenyl rings of the TMPP ligands. Reaction of [Pt(NCCH3)4][BF4]2 with two equivalents of TMPP in acetonitrile yields [PT(NCCH3)2(TMPP)2][BF4] 2, 3. Structural and spectroscopic data for 3 indicate that free rotation of the arene rings in solution is restricted due to steric influences of the two CH3CN co-ligands. Reaction of PtCl2(NCCH3)2 with two equivalents of TMPP in acetone or reaction of [Pt(NCCH3)4][BF4]2 with four equivalents of TMPP in acetone gives Pt(TMPP-O)2, 4. Reaction of PtCl2(NCCH3)2 with two equivalents of TMPP in tetrahydrofuran yields the neutral compound PtCl(TMPP)(TMPP-O), 5. Although suitable single crystals were not obtained, the structure of compound 5 was deduced from infrared and NMR spectroscopies to be a square planar molecule with one neutral TMPP ligand coordinated in an eta1 fashion and a demethylated TMPP group bound as an eta2-P,O ligand where the phosphorus atoms are trans and the other two coordination sites are occupied by a phenoxide oxygen and a Cl atom.
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.Computed Properties of C8H12B2F8N4Pd, you can also check out more blogs about21797-13-7
