Abstract

The Suzuki-Miyaura reaction of phenyl 1,4-bis(trifluoro­methylsulfonyloxy)-2-naphthoate and ethyl 3,5-bis(trifluoromethylsulfonyloxy)-2-naphthoate afforded various 1,4- and 3,5-diaryl-2-naphthoates with very good site-selectivity, respectively. The first attack occurred at the sterically more hindered positions C-1 and C-3, respectively. The selectivity can be explained by the electronic influence of the ester group.
