One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, category: catalyst-palladium, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 95464-05-4, Name is 1,1′-Bis(diphenylphosphino)ferrocene-palladium(II)dichloride dichloromethane complex, molecular formula is C35H32Cl4FeP2Pd

(Chemical Equation Presented) We describe a concise synthesis of the structurally novel fungal extremophile metabolite berkelic acid, an effort leading to an unambiguous assignment of C22 stereochemistry. Our synthetic approach was inspired by the recognition that berkelic acid displays structural characteristics reminiscent of two other fungal metabolites, spicifernin and pulvilloric acid. Based on this notion, we executed a synthesis that features a Ag-catalyzed cascade dearomatization-cycloisomerization-cycloaddition sequence to couple two natural product inspired fragments. Notably, a spicifernin-like synthon was prepared with defined C22 stereochemistry in seven steps and three purifications (24-28% overall yield). A potentially useful anti-selective conjugate propargylation reaction was developed to introduce the vicinal stereodiad. An enantioconvergent synthesis of the other coupling partner, the aromatic precursor to pulvilloric acid methyl ester, was achieved in eight steps and 48% overall yield. The total synthesis of berkelic acid and its C22 epimer was thus completed in a 10 step linear sequence and 11-27% overall yield.
