Title:
METHOD FOR PRODUCING DIARYLMETHANE COMPOUND
Document Type and Number:
WIPO Patent Application WO/2020/262144
Kind Code:
A1
Abstract:
Provided is a method for producing a diarylmethane compound that brings a compound (I) represented by formula (I), a Lewis acid, and a reducing agent into contact in the presence of an indium compound to produce a diarylmethane compound represented by formula (II). In the formula, R1 shows a halogen atom, etc., n shows an integer of 0-5, X shows a group represented by -C(=O)- or -CH(-OR2)-, R2 shows a hydrogen atom, etc., and Ar shows an optionally substituted aromatic cyclic group or an optionally substituted aromatic heterocyclic group.
