A One-pot preparation of 1,3-diarylisobenzofuran
Hamura, Toshiyuki,Nakayama, Ryosuke
, p. 1013 - 1015 (2013/09/24)
A simple, practical, and efficient method for one-pot synthesis of symmetric and unsymmetrical 1,3-diarylisobenzofurans has been developed by sequential reactions of methyl 2-formylbenzoate with two identical or different aryl metal species.
