Herein, we report a Pd-catalysed alkoxycarbonylation of alkenes based on the use of a recyclable CO2 reduction product, the crystalline and air-stable N-formylsaccharin, as a CO surrogate. The carbonylation proceeds under ambient conditions in an exceptionally complementary regioselective fashion yielding the desired branched products from styrene derivatives and valuable linear esters from alkyl-substituted alkenes.

Under anhydrous conditions, 4-phenyl-2H-chromenes were obtained in excellent yields by a cross-coupling reaction of 4-trifluoromethylsulfonyloxy-2H-chromenes with arylboronic acids, except for o-methoxyphenylboronic acid, in the presence of K2CO3 and several palladium catalysts. Although copper(I) iodide, used as a co-catalyst, showed no effect on this reaction, it was confirmed to act in the case of the coupling reaction of 4-trifluoromethylsulfonyloxy-2H-chromene with tributylphenyltin, instead of phenylboronic acid, in the presence of [Pd(PPh3)4].

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

N,N-disubstituted amines in which the amino nitrogen atom is bound to the carbon atom of an aromatic ring disubstituted in the positions ortho to the carbon atom, are prepared by allowing a primary amine and a compound in which an ortho, ortho-disubstituted aromatic compound carrying a nucleofuge substituent, to react in a basic environment in the presence of a catalytic palladium(0) complex and a ligand, the ratio of palladium complex to ligand being greater than at least 1:1. A typical embodiment involves the reaction of 2-methyl-6-ethylphenyl-trifluoromethylsulfonate and (S)-1-methoxy-2-aminopropane in the presence of bis(dibenzylideneacetone)palladium, tri-tert.-butylphosphine, and sodium tert.-butoxide to yield (S)-N-(1-methoxyprop-2-yl)-2-methyl-6-ethylphenylamine.

A conjugated copolymer having an alternate structure of 9,10-diphenylanthracene and 1,3-diphenylallene was synthesized by the Suzuki-Miyaura cross-coupling reaction with 9,10-dibororanylanthracene and 1,3-bis(4-bromophenyl)-1,3-diphenylallene. The diphenylanthracene moiety worked as an absorptive and emissive center unit in the polymer. The twisted allene moiety not only controlled conjugation length of the polymer but also suppressed formation of excimers, which realized intense pure blue fluorescence with high quantum efficiency (Phif ? 1.0) in CHCl3 solution.

Electric Literature of 95408-45-0, 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, 95408-45-0, 1,1′-Bis(di-tert-butylphosphino)ferrocene-palladium dichloride, introducing its new discovery.

The Pd-catalyzed cross coupling reactions between sp2-C halides and terminal acetylenes have been independently reported by Heck, Cassar and us in 1975. The former two methods have been developed as an extension of the Heck reaction to an acetylenic CH-bond. Ours has been discovered on the base of combination of Pd-catalyzed cross-coupling of sp2-C halides with terminal acetylenes and Cu-catalyzed alkynylation of metal complexes developed by us in the course of systematic studies on transition metal acetylide chemistry. The coupling reactions have been used extensively as a reliable method for the synthesis of eneyne-based acetylenic materials. Some recent advances of the coupling are also described.
