12. 2 (0.41 g, 0.75 mmol) and 1.0 equiv of PhNNPh (0.18 g, 1.0 mmol) in toluene, stirring was discontinued as the temperature of the reaction mixture reached 95 °C. After 5 h at reflux temperature, 0.18 g (0.25 mmol) of small colorless crystals of 2 had formed which were identified by melting point (> 300 °C) and IR spectrum after isolation and washing with n-pentane (3 × 5 mL). The yellow-brown supernatant contained ca. 36% yield of 1, 17% of Mes*H, and 12% of unreacted PhNNPh. 1 was isolated after recrystallization from n-pentane (20 mL) at -20 °C for 2 days in 9.0% yield (0.06 g).
