摘要： The disclosure provides methodology for the synthesis of mono-alkylated cyclopentadiene structures, which can be obtained via fulvene intermediates. In one embodiment, the cyclopentadiene ring is substituted with a trialkylsilyl moiety, which enables the further reaction with certain metal halides to form metal adducts. For example, the monoalkyl cyclopentadienes substituted with a trimethylsilyl group can be reacted with TiCl4 to provide R*CpTiCl3 complexes, wherein R* is a group of the formula
wherein R1 and R2 are as defined herein.-

摘要： Systems and methods for formation of highly reactive alkali dendrites are provided. For example, in some embodiments alkali metals are dissolved in ammonia to form metal electrides after which the ammonia is removed via vacuum to reveal highly activated metal surfaces in the form of crystalline alkali dendrites. The alkali dendrites can mimic powders but have the advantage of being freshly prepared from inexpensive and readily available metal sources. These uniquely activated metals exhibit enhanced reactivity comparatively to similar off the shelf sources of the corresponding metals. For example, the dendrites can have about 100 times greater surface area than conventional metal sources and/or be about 19 times more reactive than powders that serve as the industry standard for the preparation of organometallic compounds. After surface activation, these metals can be used to prepare various organometallic reagents.

摘要： In a cross coupling reaction, in a case where a halogen atom is selected as the leaving group of the raw material compound, a harmful halogen waste forms as a by-product after the reaction, and disposal of the waste liquid is complicated and environmental burden is high. In a carbon-hydrogen activation cross coupling reaction which requires no halogen atom as the leaving group, although no halogen waste forms as a by-product, the reaction substrate is considerably restricted, and the reaction remains a limited molecular construction method.A method for producing an aromatic compound, which comprises subjecting an aromatic nitro compound and a boronic acid compound to a cross coupling reaction in the presence of a metal catalyst.

摘要： Processes of forming Csp2—Csp3 bonds at the allylic carbon of a cyclic allylic compound starting material are disclosed, in which a racemic mixture of a cyclic allylic compound having a leaving group attached to the allylic carbon is reacted with a compound having a nucleophilic carbon atom in the presence of a Rh(I), Pd(II) or Cu(I) pre-catalyst and a chiral ligand. The reaction products containing the newly-formed Csp2—Csp3 bond are generated in high stereoisomeric excess, and may therefore serve as important organic building blocks in the preparation of new agrochemicals and pharmaceuticals.
