Title:
METHOD FOR PRODUCING DIARYL DERIVATIVE, NOVEL BINAPHTHYL DERIVATIVE, METHOD FOR PRODUCING ARENE DERIVATIVE AND NOVEL ARENE DERIVATIVE
Document Type and Number:
WIPO Patent Application WO/2011/111762
Kind Code:
A1
Abstract:
Disclosed are a novel binaphthyl derivative, a novel formylarene derivative and a method capable of producing diaryl derivatives having an asymmetric structure or formylarenes having two specific substituent groups. Using a diformyl-diaryl derivative having axial asymmetry or a formylarene as the starting material, trifluoromethanesulfonic acid and N,N'-diiodo-5,5-dimethylhydantoin are reacted under mild conditions and a formyldiaryl derivative with trifluoromethylsulfonyloxy groups introduced at the 4 and 4' positions or a formylarene derivative with a trifluoromethylsulfonyloxy group and iodine introduced therein is obtained in a single reaction process.
