Substrate screening for [CoII(TPP)] catalyzed synthesis of azobenzenes from o-amine substituted azides *. * All reactions were carried out with 0.3 mmol of azide, [CoII(TPP)] (5 mol%) in 4 mL of toluene. The reaction mixtures were bubbled with dinitrogen for 15 min prior to thermostatting at the stated temperature for 18 h. Isolated yields are reported.
