Disubstituted pyridine/pyrimidine ferrocenyl complexes have been obtained by mechanically induced Sukuzi coupling reactions in the solid state. It is shown that the solventless process is much faster, and more selective, than the same reaction carried out in solution. The synthesis and structure of the complex [Fe(eta5-C5H4-4-C5H 4N)(eta5-C5H4-3-C 4H3N2)] are reported as a test case.

A straightforward synthesis of cyclopropenylidene-stabilized phosphenium cations 1 a-g through the reaction of [(iPr2N)2C 3+Cl]BF4 with secondary phosphines is described. Their donor ability was evaluated by analysis of the CO stretching frequency in Rh complexes [RhCl(CO)L2](BF4)2 and electrochemical methods. The cyclopropenium ring induces a phosphite-type behavior that can be tuned by the other two substituents attached to the phosphorus atom. Despite of the positive charge that they bear, phosphenium cations 1 a-g still act as two-electron donor ligands, forming adducts with PdII and PtII precursors. Conversely, in the presence of Pd0 species, an oxidative insertion of the Pd atom into the C carbene-phosphorus bond takes place, providing dimeric structures in which each Pd atom is bonded to a cyclopropenyl carbene whi Copyright

A new heterometallic dyad composed of a zinc porphyrin linked by bisethynyl quaterthiophene to a gold porphyrin was synthesized according to a stepwise modular approach. The latter dyad and the parent reference compounds (porphyrin-ethynylquaterthiophene) were characterized by electrochemistry, spectroelectrochemistry, and femtosecond transient absorption spectrocopy. We showed that light excitation of the zinc or the gold porphyrin induces a very fast and quantitative charge separation over a distance of 25 A which occurs through a superexchange mechanism. The lifetime of the charge-separated state is 3.3 ns in toluene and 100 ps in dichloromethane, and it recombines to the ground state in both solvents.

(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.

Utilization of the OBO derivative of the pyruvate ester allowed the application of palladium catalyzed arylation reactions together with subsequent alkylation, under basic conditions. Moreover, the OBO protecting group could be easily removed in one step to provide access to a wide range of substituted pyruvate derivatives.

(Figure Presented) We report the synthesis of several unique, boron-rich pincer complexes derived from mcarborane. The SeBSe and SBS pincer ligands can be synthesized via two independent synthetic routes and are metalated with Pd(II). These structures represent unique coordinating motifs, each with a Pd?B(2) bond chelated by two thio- or selenoether ligands. This class of structures serves as the first example of boron?metal pincer complexes and possesses several interesting electronic properties imposed by the m-carborane cage. Copyright

An efficient method for the enantioselective synthesis of beta-tertiary beta-amino alcohol derivatives through Pd-catalyzed decarboxylative cycloaddition of vinylethylene carbonates with imines was developed. By using a palladium complex generated in situ from [Pd2(dba)3]·CHCl3 and phosphoramidite L2 as a catalyst under mild reaction conditions, the process provided 4-substituted-4-vinyloxazolidines in good to high yields with high levels of enantio- and diastereoselectivities.
