Figure 10: (a) Absorption spectral changes recorded at 10 min interval for the reaction between 3 (0.43×10-4 M) and NaBH4 (1.71×10-4) in CH3OH at 320 K; (b) similar data recorded at 2 min interval for the reaction between 3 (0.12×10-4 M) and K3[Fe(CN)6] (0.13×10-4 M) in CH3OH–H2O 3:1 v/v at 320 K; (c) similar data recorded at 16 min interval for the reaction between 3 (0.1×10-4 M) and Me3N→O (0.7×10-4 M) in CH3OH at 323 K.
