摘要:7,7-双(三氟甲基磺酰氧基)-2-降冰片烯(1A),1-三氟甲基磺酰氧基-1-苯基乙烯(2A),2-甲基-1-环己烯-1-基三氟甲磺酸酯(3A)和4-Camphenyl Triflate的溶剂分解(4A)在添加了mgi 2和mgbr 2的二硫化碳或乙醚中,产生相应的卤化物5B-E,6B-C,7B-C和8B-C的混合物.与卤化镁的配位有利于三氟甲磺酸酯基团的电离.已发现与mgi 2的反应是二级反应,反应活性是mgbr 2的约50倍.中间阳离子5-8的选择性尽管溶剂分解速率相差十次以上的三次幂,但是朝向亲核试剂的mgi 2和mgbr 2几乎是恒定的.给出了恒定选择性原理的理论解释.

标题:Methods for the synthesis of organic sulfides by using sulfides and organic sulfur-indium complexes
发明人：LEE PHIL-HO
权利人:LEE PHIL-HO; KNU INDUSTRY COOPERATION FOUND
摘要:The present invention relates to a novel synthesis method for the formation of carbon-sulfur bonds by the reaction of an organic sulfur-indium complex with nucleophile in the presence of a palladium catalyst. The present invention provides a synthesis method to prepare several kinds of organic sulfides which are difficult to be prepared by the conventional synthesis methods. A short reaction time and quantitative yield are the advantages of this method. In addition, several kinds of organic sulfide can be prepared by the selection of nucleophile and organic sulfur-indium complex to be used.

摘要:Stable alpha -substituted boronic esters, e.g. for use in peptide synthesis, are prepared by reacting a substituted alkene of the formula: with a disubstituted borane of the formula: wherein: (i) R1 and R2 are each selected from various groups which are preferably not leaving groups; (ii) X is halogen or other leaving group; (iii) Y is H or lower alkyl; (iv) Q1 and Q2 are each selected from various groups which are preferably such that the borane is non-hydrolyzable, and particularly Q1 and Q2 together may represent a residue of a diol such as catechol or pinanediol.

摘要:The present invention is a one-step method for efficiently converting carbon-hydrogen bonds into carbon-carbon bonds using a combination of aryl halides, a substrate, and a copper salt as catalyst. This method allows faster introduction of complex molecular entities, a process that would otherwise require many more steps. This invention is particularly relevant for the organic synthesis of complex molecules such as, but not limited to, pharmacophores and explosives.
