Abstract

The d ⁹d ⁹ Pt ₂ ^I,I(tfepma) ₂Cl ₂ (1) compound (tfepma = ((CF ₃CH ₂O) ₂P) ₂NCH ₃), d ⁷-d ⁹ Pt ₂ ^I,III (tfepma) ₂Cl ₄ (2) and d ⁷-d ⁷ Pt ₂ ^III,III(tfepma) ₂Cl ₆ (3), homologous suite of compounds have been prepared. Irradiation of 3 with visible light generates 2 in solution in the presence of 2,3-dimethyl-1,3-butadiene with a quantum efficiency of ∼38%. The evolution of Cl ₂ upon solid-state photolysis of 3 represents the first example of the thermodynamically unfavorable halogen elimination without the use of a chemical trap.
