20090216017 | PROCESS FOR PRODUCING BIARYL COMPOUND - A process for producing a biaryl compound, characterized by reacting an arylhydrazine compound, hydrogen peroxide and an aryl compound. When the reaction is conducted in the presence of a given metal or a compound of the metal or in the presence of a metal oxide obtained by reacting the given metal or a compound of the metal with hydrogen peroxide, then the yield of the biaryl compound is improved. | 08-27-2009 |
20100087643 | METHOD FOR PRODUCING OPTICALLY ACTIVE 2-ARYLPIPERAZINE DERIVATIVE - The objective of the present invention is to produce an optically active 2-arylpiperazine derivative useful as a synthetic intermediate for pharmaceutical products and agricultural chemicals from inexpensive and readily available starting material by an industrially practicable method. The objective can be accomplished by treating an optically active substituted aminodiol derivative produced from an optically active styrene oxide derivative with a sulfonating agent in the presence of a base, and then reacting an amine compound to obtain the 2-arylpiperazine derivative. Especially, an optically active 1-unsubstituted-2-arylpiperazine derivative can be produced by treating an optically active 1-allyl-2-arylpiperazine derivative with water in the presence of a transition metal catalyst for deallylation. | 04-08-2010 |
