One-electron oxidation of the non-innocent 1,2,4-diazaphospholide anion [3,5-R2dp]-(R = Cy(1),iPr(2),or Ph(3)) by AsCl3 generated a diagonal paddlewheel diarsine [L2(As-As)L2](L = η1,η1-3,5-R2dp,R = C
Metal-catalyzed asymmetric Friedel-Crafts alkylation of indoles with α,β-unsaturated carbonyl compounds is a powerful carbon-carbon bond forming transformation in organic chemistry.
Aromatic amines are important intermediates in synthesis of several nitrogen containing biologically active compounds,agrochemicals,dyes,polymers,etc.
Transition-metal-catalyzed asymmetric hydrogenation is one of the most useful reactions for the synthesis of optical compounds.
Transfer hydrogenation(TH) has recently become the center of research in hydrogenation science.A vast number of metal catalysts have shown excellent activity in TH,such as Pd,Ru,Ir,Os,Au and so on.
Reduction of amides is one of versatile synthetic methodologies for producing the corresponding amines.In general,stoichiometric or even excess amounts of reducing hydride reagents have been utilized,
轴手性二芳基化合物广泛存在于天然产物、药物和材料中,同时也可以作为配体或催化剂在有机合成中起着不可或缺的作用[1].目前,合成轴手性二芳基化合物的方法主要有不对称偶联、不对称官能化、中心手性向轴手性转移、动态动力学拆分和动力学拆分等方法[2].
Given the great significance of the difluoromethylene group(CF2) in drug discovery,medicinal chemistry and life science,the development of new synthetic approach for the assembly of fluorinated small
Hyperconjugation,a weak interaction in organic chemistry,can have a strong effect on aromaticity,leading to the concept of hyperconjugative aromaticity,which was first proposed by Mulliken in 1939[1]a
Experimentally,osmapentalene complexes with 16 and 18 valence electrons osmiums were prepared by the addition of electrophile and nucleophiles to osmapentalynes,[1-2] respectively,thus demonstrating t
