摘要： PROBLEM TO BE SOLVED: To provide a useful new biphenyl compound and to provide a method for producing the compound.
SOLUTION: The new 4-(cyanomethyl)-2-fluoro-3'-fluoro-4'-(trifluoromethyl) biphenyl can be produced by carrying out coupling reaction of a 4-halo-2- fluorobenzotrifluoride with a 1-halo-4-(cyanomethyl)-2-fluorobenzene. It is preferable and recommended on handling that a halogen at 4-position of the first raw material compound and a halogen at 1-position of the second raw material compound are each bromine from the viewpoints of yield of the coupling reaction and economical efficiency. The new compound is expected for utilization to luminescent element materials for organic electroluminescence displays and utilization as an intermediate for medicines and agrochemicals and functional materials.

摘要： PROBLEM TO BE SOLVED: To provide a new biphenyl compound. SOLUTION: The biphenyl compound, 4-hydroxymethyl-3',5'-bis(trifluoromethyl)biphenyl, is obtained by making 4-bromobenzyl alcohol as a Grignard reagent of 4-bromobenzyl ether, coupling the same with 3,5-bis(trifluoromethyl)bromobenzene in the presence of a metal catalyst to deprotect the protective group R. Furthermore, a hydroxy group in the obtained biphenyl compound is converted to a leaving group, then is reacted with cyanide ions to produce 4-cyanomethyl-3',5'-bis(trifluoromethyl)biphenyl. The biphenyl compound is a new compound and is useful as a precursor for organic fluorescent substances. COPYRIGHT: (C)2011,JPO&INPIT
