Reaction: cis-1,4-Dichloro-1,4-dinitrosocyclohexane + ¹O₂^* ® products and/or physical quenching
Reference Reaction: DPBF + ¹O₂^* ®
Solvent: CH₂Cl₂, 69%, MeOH, 31%

k = 9.2 × 10⁹(L mol^-1 s^-1)

Experimental method: Photolysis
Data type: Derived from steady state measurements using indicator

Photosensitizer = Chlorophyll a; Indicator = 1,3-Diphenylisobenzofuran, k for indicator = 8 × 10⁸ L/(mol·s); used solvent k_d = 2.1 × 10⁴ s^-1; Assumed that quenching is due to equilibrium mixture of this species with 1,4-dichloro-2,3-diazabicyclo[2.2.2]oct-2-ene 2,3-dioxide.

k = 1.2 × 10¹⁰(L mol^-1 s^-1)

Experimental method: Chemical reaction
Data type: Derived from steady state measurements using indicator

Indicator = Rubrene, k for indicator = 4.0 × 10⁷ L/(mol·s); used solvent k_d = 2.1 × 10⁴ s^-1; ¹O₂* from (PhO)₃PO₃; Assumed that quenching is due to this species in equilibrium with 1,4-dichloro-2,3-diazabicyclo[2.2.2]oct-2-ene 2,3-dioxide.
