专利号:US-5827794-A 优先权日:1994-02-22 标 题 :Supported highly-polar liquid phase chiral sulfonated binap catalyst for asymmetric synthesis of optically active compounds 发明人:DAVIS MARK E; WAN KAM TO 权利人:CALIFORNIA INST OF TECHN 摘要:The present invention relates to water soluble chiral sulfonated 2,2'-bis(diphenylphosphino)-1,1'-binaphthyl and its use as organometallic catalysts for asymmetric synthesis of optically active compounds. Asymmetric reactions of the present invention include those reactions in which organometallic catalysts are commonly used. Such reactions include, but are not limited to, reduction and isomerization reactions on unsaturated substrates and carbon--carbon bond forming reactions. Examples of such reactions include, but are not limited to, hydrogenation, hydroboration, hydrosilylation, hydride reduction, hydroformylation, alkylation, allylic alkylation, arylation, alkenylation, epoxidation, hydrocyanation, disilylation, cyclization and isomerization reactions. n The catalysts of the present invention provide the advantage of functioning in the presence of water without loss in enantioselectivity relative to the nonsulfonated BINAP catalyst in an organic solvent. As a result, the catalysts of the present invention may be employed in water, water miscible solvents, in aqueous--organic two phase solvent systems and in supported aqueous phase catalysts in organic solvents without loss in enantioselectivity. Further, the catalysts of the present invention may also be effectively employed in highly polar solvents such as primary alcohols and ethylene glycol. n The present invention also relates to a method for conducting asymmetric reactions on prochiral unsaturated bonds contained within a compound using the water soluble chiral sulfonated 2,2'-bis(diphenylphosphino)-1,1'-binaphthyl organometallic catalysts of the present invention.

The method for β-cyc-assisted synthesis of an In-V group quantum dot comprises: preparing a β-cyc-containing precursor solution of an In source and a V group element source, and subjecting it to a hydrothermal reaction; extracting a stock solution after the hydrothermal reaction by using an organic solvent; removing β-cyc from the stock solution, washing same with water and then extracting same; and heating and concentrating same to obtain a high-concentration In-V group quantum dot solution. With regard to the β-cyc-assisted synthesis of an In-V group quantum dot, the In-V group quantum dot synthesized with the assistance of β-cyc is prepared by using the method for β-cyc-assisted synthesis of an In-V group quantum dot. The use of β-cyc-assisted synthesis of an In-V group quantum dot is the use of the β-cyc-assisted synthesis of an In-V group quantum dot in the field of photovoltaics, and the field of photovoltaics comprises solar cells, photoelectrochemical hydrogen production and photoelectric detectors. Compared with traditional synthesis methods, this synthesis method has the advantages of green and environmentally friendly raw materials, a simple and safe process, a simple and convenient device, efficient and economic synthesis, and being low cost.
