Electric Literature of 52522-40-4, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 52522-40-4, Tris(dibenzylideneacetone)dipalladium-chloroform, introducing its new discovery.
Synthesis and decomposition behavior of a C2-symmetrical palladium(IV) Spirocyclic complex
A novel palladium(IV) complex consisting of a C2-symmetrical palladaspirocycle framework and an ether ligand was assembled only in a single step from commercially available Pd2(dba)3, tetrachloro-1,2-benzoquinone (o-chloranil), and norbornene. The solid-state structure was confirmed by X-ray analysis of a THF complex. The ligand exchange from diethyl ether to pyridine converted the trigonal-bipyramidal complex to a distorted-octahedral bis(pyridine) complex. Similar palladium(IV) spirocyclic complexes were also formed from the reaction of Pd2(dba)3 with o-chloranil and benzonorbornadiene. The benzonorbornadiene-derived complexes exhibited pronounced stability in both the solid state and solution. The complete decomposition of the mono(pyridine) complex required several hours in C6D6 at 70C, and the addition of extra pyridine retarded the decomposition rate. Benzonorbornadiene was obtained as the main organic product, together with two isomeric adducts between o-chloranil and benzonorbornadiene. On the other hand, the decomposition of the pyridine complex took place within 15 min even at -40 to -50C, upon exposure to HCl in a CDCl3 solution.
