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)CoII 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.
