摘要:Methods for the synthesis of polycyclic aromatic hydrocarbons and synthesis platforms for performing such syntheses are provided. Methods and platforms are provided that allow for the synthesis of aza-polycyclic aromatic hydrocarbons by an expedient ring assembly. Methods and platforms allow for a modular approach to synthesis that provide multiple new C—C bonds in sequential pericyclic reactions, thus giving access to compounds with multiple axes of substitution.

标 题:Synthesis of bromobiphenyls
发明人：LANG JOHN F; GURUSAMY NARAYANASAMY
权利人:MALLINCKRODT SPEC CHEM
摘要:Bromobiphenyls (such as 2-fluoro-4-bromobiphenyl) are synthesized by reacting together a phenylboronic acid (such as phenylboronic acid) and a bromoiodobenzene (such as 2-fluoro-4-bromoiodobenzene). The reaction generally takes place with the aid of a catalyst (such as palladium in a zero valance state) and an inert solvent (such as fluorobenzene). Control of temperature is very important to obtain both an acceptable reaction rate and an acceptable level of terphenyl byproduct.

摘要:To provide a fluorescent having low toxicity and high quantum yield, and a method for producing the same. The fluorescent is a compound comprising each one of I, III and VI group elements having a chalcopyrite structure, has a particle diameter of 0.5 to 20.0 nm and a quantum yield of at least 3% but not more than 30% at room temperature. The fluorescent is produced by: mixing a first solution (solution A), which is prepared by dissolving and mixing copper (I) salt and indium (III) salt in a solution added with a complexing agent coordinating copper (I) and indium (III), with a second solution (solution C) in which a sulfur compound is dissolved; ripening the mixed solution for a predetermined amount of time as a pretreatment; heat-treating the ripened solution under predetermined heat conditions; mixing the ripened solution with the second solution (solution C); and heating thus obtained mixed solution under predetermined synthesis conditions. In addition, a product produced by this production method is subjected to compositing treatment with ZnSe, ZnS or the like to improve the quantum yield.
