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
1,4-双(三氟甲基磺酰氧基)-2-萘甲酸苯酯与3,5-双(三氟甲基磺酰氧基)-2-萘甲酸乙酯的Suzuki-Miyaura反应得到各种1,4-和3,5-二芳基-2-萘甲酸乙酯分别具有非常好的位点选择性。第一次攻击分别发生在空间较受阻的位置C-1和C-3。选择性可以通过酯基团的电子影响来解释。 催化-钯-铃木-宫浦反应-位点选择性-萘衍生物
