  Regiochemistry of the coupling of aryl radicals with nucleophiles derived from the naphthyl system. Experimental and theoretical studies

  摘要：

  We here report the photostimulated reaction of unactivated aromatic halides with ambident nucleophiles derived from the naphthyl system such as 1- and 2-naphthylamide, 2-naphthoxide, 2-naphthalenethiolate, and 2-naphthaleneselenate ions, by the S(RN)1 mechanism of nucleophilic substitution. According to our experimental results, C-arylation in position 1 of the naphthyl moiety is the only reaction observed with 2-naphthoxide ions and it is favored over N-arylation with 1- and 2-naphthylamide ions. Heteroatom arylation is preferred over C-arylation with 2-naphthalenethiolate ions while it is the only observed reaction with 2-naphthaleneselenate ions. A theoretical study was carried out to explain the regiochemistry of the system. In competition experiments, 2-naphthalenethiolate ions proved to be 1.8 +/- 0.2 times more reactive than 2-naphthoxide ions for C-substitution toward p-anisyl radicals in liquid ammonia.
