| 英文摘要 | A heterobimetallic complex, (TPFC) Sn-Co(TAP) (TPFC = 5,10,15-tris(pentafluorophenyl) corrole, TAP = 5,10,15,20-tetrakis(p-methoxyphenyl) porphyrin), was synthesized. The complex featured a Sn-Co bond with a bond dissociation enthalpy (BDE) of 30.2 +/- 0.9 kcal mol(-1) and a bond dissociation Gibbs free energy (BDFE) of 21.0 +/- 0.2 kcal mol(-1), which underwent homolysis to produce the (TPFC) Sn radical and (TAP) Co-II under either heat or visible light irradiation. The novel tin radical (TPFC) Sn, being the first four-coordinate tin radical observed at room temperature, was studied spectroscopically and computationally. (TPFC) Sn-Co(TAP) promoted the oligomerization of aryl alkynes to give the insertion products (TPFC) Sn-(CH=C(Ar))(n)-Co(TAP) (n = 1, 2, or 3) as well as 1,3,5-triarylbenzenes. Mechanistic studies revealed a radical chain mechanism involving the (TPFC) Sn radical as the key intermediate. |
