摘要:Provided herein are a method of Ru(II)-catalyzed enantioselective synthesis of a cyclic compound and cyclic compounds formed therefrom. The method includes providing a precursor compound having an unfunctionalized C—H bond and activating the unfunctionalized C—H bond by reacting the precursor compound in the presence of co-catalysts including a Ru(II) arene complex and a chiral transient directing group (CTDG).

摘要:Provided is a method for manufacturing a catalyst with which it is possible to obtain a supported metal ammonia synthesis catalyst, in which there are restrictions in terms of producing method and producing facility, and particularly large restrictions for industrial-scale producing, in a more simple manner and so that the obtained catalyst has a high activity. This method for manufacturing an ammonia synthesis catalyst includes: a first step for preparing 12CaO·7Al 2 O 3 having a specific surface area of 5 m 2 /g or above; a second step for supporting a ruthenium compound on the 12CaO·7Al 2 O 3 ; and a third step for performing a reduction process on the 12CaO·7Al 2 O 3 supporting the ruthenium compound, obtained in the second step. This invention is characterized in that the reduction process is performed until the average particle diameter of the ruthenium after the reduction process has increased by at least 15% in relation to the average particle diameter of the ruthenium before the reduction process.

摘要:The present invention relates to a vinyl keto ester and intermediates of its synthesis, wherein the vinyl moiety of the vinyl hydroxy ester and of the intermediates is partly or fully deuterated. Furthermore, the present invention relates to two alternative methods of preparing said vinyl keto ester. The first method is a multi-step approach comprising the steps of providing a carboxylic acid that comprises a geminal diol moiety protected by a photolabile protecting group, vinylating said carboxylic acid using vinyl acetate, and cleaving the protecting group by applying UV light. The second method is a one-step approach of reacting a carboxylic acid that comprises an additional carbonyl moiety with acetylene in the presence of a metal catalyst. In both methods, the compounds used may be fully or partly deuterated.

摘要:The present application discloses complexes useful as catalysts for organic chemical synthesis including hydrogenation and dehydrogenation of unsaturated compounds or dehydrogenation of substrates. The range of hydrogenation substrate compounds includes esters, lactones, oils and fats, resulting in alcohols, diols, and triols as reaction products. The catalysts of current application can be used to catalyze a hydrogenation reaction under solvent free conditions. The present catalysts also allow the hydrogenation to proceed without added base, and it can be used in place of the conventional reduction methods employing hydrides of the main-group elements. Furthermore, the catalysts of the present application can catalyze a dehydrogenation reaction under homogenous and/or acceptorless conditions. As such, the catalysts provided herein can be useful in substantially reducing cost and improving the environmental profile of manufacturing processes for variety of chemicals.
